yes.. you all asked for it (well at least 10...) 
here are the ansi vt100 codes for cursor control. 
it is somwhat edited, since a lot was DEC specific and other stuff.
if you want the whole file.. just mail me 
but this is the good stuff:




This file describes information needed for controlling the VT100 terminal from
a remote computer.  All of the information was derived from the VT100 user's
manual, Programmer's Information section.  Full documentation can be obtain
from DIGITAL'S Accessory and Supplies Group.

NOTE 1: Codes 0152-0156 and 0164-0170 are used to draw rectangular grids" each
piece of this set is contiguous with other so the lines formed will be
unbroken.

NOTE 2: Codes 0157-0163 give better vertical resolution than dashes and
underlines when drawing graphs; using these segments, 120 x 132 resolution may
be obtained in 132 column mode with the Advanced Video Option installed.

* Terminal Control Commands *
*****************************

Control Characters
------------------

        The control characters recognized by the VT100 are listed below.  All
other control characters cause no action to be taken.

        Control characters (codes 00 - 037 inclusive) are specifically excluded
from the control sequence syntax, but may be embedded within a controlsequence.
Embedded control characters are executed as soon as they are encountered by the
VT100.  The processing of the control sequence then continues with the next
character recieved.  The exceptions are: if the <ESC> character occurs, the
current control sequence is aborted, and a new one commences beginning with the
<ESC> just recieved.  If the character <CAN> (030) or the character <SUB> (032)
occurs, the current control sequence is aborted.  The ability to embed control
characters allows the synchronization characters XON and XOFF to be interpreted
properly without affecting the control sequence.

------------------------------------------------------------------------------
<NUL>           0000    Ignored on input; not stored in buffer
<ENQ>           0005    Transmit ANSWERBACK message
<BEL>           0007    Sound bell
<BS>            0010    Move cursor to the left one position, unless it is at
                        the left margin, in which case no action is taken.
<HT>            0011    Move cursor to the next tab stop, or to the right
                        margin if no further tabs are set.
<LF>            0012    Causes either a line feed or new line operation (See
                        new line mode.)
<VT>            0013    Same as <LF>.
<FF>            0014    Same as <LF>.
<CR>            0015    Move the cursor to the left margin of the current line.
<SO>            0016    Invoke the G1 character set, as designated by the SCS
                        control sequence.
<SI>            0017    Invoke the G0 character set, as selected by the <ESC>(
                        sequence.
<DC1>           0021    Causes terminal to resume transmission (XON).
<DC3>           0023    Causes terminal to stop transmitting all codes except
                        XOFF and XON (XOFF).
<CAN>           0030    If sent during a control sequence, the sequence id
                        immediately terminated and not executed.  It also
                        causes the error character (checkerboard) to be
                        displayed.
<SUB>           0032    Same as <CAN>.
<ESC>           0033    Introduces a control sequence.
<DEL>           0177    Ignored on input; not stored in buffer.


        The VT100 is an upward and downward software compatible terminal; that
is, previous DIGITAL video terminals have DIGITAL's private standards for
control sequences. The American National Standards Institute has since
standardized escape and control sequences in terminals in documents X3.41-1974
and X3.64-1977.

        The VT100 is compatible with both the previous DIGITAL standard and
ANSI standards.  Customers may use existing DIGITAL software designed around
the VT52 or new VT100 software.  The VT100 has a "VT52 compatible" mode in
which the VT100 responds to control sequences like a VT52.  In this mode, most
of the new VT100 features cannot be used.

        Throughout this document references will be made to "VT52 mode" or
"ANSI mode".  These two terms are used to indicate the VT100's software
compatibility.


NOTE: The ANSI standards allow the manufacturer flexibility in implementing
each function.  This document describes how the VT100 will respond to the
implemented ANSI central function.

Definitions
-----------

        Control Sequence Introducer (CSI) - An escape sequence that provides
                supplementary controls and is itself a prefix affecting the
                interpretation of a limited number of contiguous characters.
                In the VT100, the CSI is: <ESC>[

        Parameter:  (1) A string of zero or more decimal characters which
                represent a single value.  Leading zeros are ignored.  The
                decimal characters have a range of 0 (060) to 9 (071).
                (2) The value so represented.

        Numeric Parameter:  A parameter that represents a number, designated by
                Pn.

        Selective Parameter:  A parameter that selects a subfunction from a
                specified set of subfunctions, designated by Ps.  In general, a
                control sequence with more than one selective parameter causes
                the same effect as several control sequences, each with one
                selective parameter, e.g., CSI Psa; Psb; Psc F is identical to
                CSI Psa F CSI Psb F CSI Psc F.

        Parameter String:  A string of parameters separated by a semicolon.

        Default: A function-dependent value that is assumed when no explicit
                value, or a value of 0, is specified.

        Final character:  A character whose bit combination terminates an
                escape or control sequence.


        EXAMPLE:  Control sequence to turn off all character attributes, then
        turn on underscore and blink attributes (SGR).  <ESC>[0;4;5m

                Sequence:


                       Delimiters
                          / \
                         /   \
                         |   |
                        \ / \ /
                <ESC>[ 0 ; 4 ; 5 m
                ^^^^^^ ^   ^   ^ ^
                |||||| |   |   | |
                \||||/  \  |  /  +------Final character
                 \||/    \ | /
                 CSI   Selective
                       Parameters


                The octal representation of this string is:

                        033 0133 060 073 064 073 065 0155
                      <ESC>   [   0   ;   4   ;   5    m


                Alternate sequences which will accomplish the same thing:

                        1) <ESC>[;4;m

                        2) <ESC>[m
                           <ESC>[4m
                           <ESC>[5m

                        3) <ESC>[0;04;005m


Control Sequences
-----------------

        All of the following control sequences are transmitted from the Host to
VT100 unless otherwise noted.  All of the control sequences are a subset of
those defined in ANSI X 3.64 1977 and ANSI X 3.41 1974.

        The following text conforms to these formatting conventions:

                1) Control characters are designated by angle brackets (e.g.
                        the Escape character is <ESC>).

                2) Parameters are indicated by curly braces.

                3) Parameter types usually are indicated as one of:

                        {Pn}    A string of digits representing a numerical
                                value.

                        {Ps}    A character that selects an item from a list.

                        {a-z}   Any lowercase sequence of one44 or more
                                characters in braces represent a value to be
                                entered (as in {Pn}), and the name in the
                                braces will be referred to in explanatory text.

                4) Spaces in the control sequence are present for clarity and
                        may be omitted.  Spaces which are required will be
                        surrounded by single quotes: ' '.

                5) All other characters are literals.





CPR     Cursor Position Report          VT100 to Host

        <ESC>[ {Pn} ; {Pn} R            Default Value: 1

        The CPR sequence reports the active position by means of the
        parameters.  This sequence has two parameter values, the first
        specifying the line and the second specifying the column.  The default
        condition with no parameters present, or parameters of 0, is equivelent
        to a cursor at home position.

        The numbering of the lines depends upon the state of the Origin Mode
        (DECOM).

        This control sequence is sent in reply to a device status report (DSR)
        command sent from the host.



CUB     Cursor Backward                 Host to VT100 & VT100 to Host

        <ESC>[ {Pn} D                   Default Value: 1

        The CUB sequence move the cursor to the left.  The distance moved is
        determined by the parameter.  If the parameter missing, zero, or one,
        the cursor is moved one position.  The cursor cannot be moved past the
        left margin.  Editor Function.


CUD     Cursor Down                     Host to VT100 & VT100 to Host

        <ESC>[ {Pn} B                   Default value: 1

        Moves the cursor down a number of lines as specified in the parameter
        without changing columns.  The cursor cannot be moved past the bottom
        margin.  Editor Function.


CUF     Cursor Foreward                 Host to VT100 & VT100 to Host

        <ESC>[ {Pn} C                   Default Value: 1

        The CUF sequence moves the cursor to the right a number of positions
        specified in the parameter.  The cursor cannot be moved past the right
        margin.  Editor Function.


CUP     Cursor Position

        <ESC>[ {Pn} ; {Pn} H            Default Value: 1

        The CUP sequence moves the curor to the position specified by the
        parameters.  The first parameter specifies the line, and the second
        specifies the column.  A value of zero for either line or column moves
        the cursor to the first line or column in the display.  The default
        string (<ESC>H) homes the cursor.  In the VT100, this command behaves
        identically to it's format effector counterpart, HVP.

        The numbering of the lines depends upon the state of the Origin Mode
        (DECOM).  Editor Function.


CUU     Cursor Up                       Host to VT100 & VT100 to Host

        <ESC>[ {Pn} A                   Default Value: 1

        Moves the cursor up without changing columns.  The cursor is moved up a
        number of lines as indicated by the parameter.  The cursor cannot be
        moved beyond the top margin.  Editor Function.


DA      Device Attributes               Host to VT100 & VT100 to Host

        <ESC>[ {Pn} c                   Default Value: 0

        1) The host requests the VT100 to send a DA sequence to indentify
           itself.  This is done by sending the DA sequence with no parameters,
           or with a parameter of zero.

        2) Response to the request described above (VT100 to host) is generated
           by the VT100 as a DA control sequencewith the numeric parameters as
           follows:

                Option Present                  Sequence Sent
                ---------------------------------------------
                No options                      <ESC>[?1;0c

<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>,
<<<I doubt if alot of these DEC commands work..a few do.. (like scroll areas)>>
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

DECALN  Screen Alignment Display (DEC private)

        <ESC># 8

        This command causes the VT100 to fill it's screen with uppercase Es for
        screen focus and alignment.


DECANM  ANSI/VT52 Mode (DEC Private)

        This is a private parameter to the SM and RM control sequences.  The
        reset state causes only VT52 compatible escape sequences to be
        recognized.  The set state causes only ANSI compatible escape sequences
        to be recognized.  See the entries for MODES, SM, and RM.


DECARM  Auto Repeat Mode (DEC Private)

        This is a private parameter to the SM and RM control sequences.  The
        reset state causes no keyboard keys to auto-repeat, the set state
        causes most of them to.  See MODES, SM, and RM.


DECAWM  Autowrap Mode (DEC Private)

        This is a private parameter to the SM and RM control sequences.  The
        reset state prevents the cursor from moving when characters are
        recieved while at the right margin.  The set state causes these
        characters to advance to the next line, causing a scroll up if required
        and permitted.  See MODES, SM, and RM.


DECCKM  Cursor Keys Mode (DEC Private)

        This is a private parameter to the SM and RM control requences.  This
        mode is only effective when the terminal is in keypad application mode
        (DECPAM) and the ANSI/VT52 mode (DECANM) is set.  Under these
        conditions, if this mode is reset, the cursor keys will send ANSI
        cursor control commands.  If setm the cursor keys will send application
        function commands (See MODES, RM, and SM).


DECCOLM Column Mode (DEC Private)

        This is a private parameter to the SM and RM control sequences.  The
        reset state causes an 80 column screen to be used.  The set state
        causes a 132 column screen to be used.  See MODES, RM, and SM.


DECDHL  Double Height Line (DEC Private)

        Top Half:       <ESC>#3
        Bottom Half:    <ESC>#4

        These sequences cause the line containing the cursor to become the top
        or bottom half of a double-height, double width line.  The sequences
        should be used in pairs on adjacent lines with each line containing the
        same character string.  If the line was single width single height, all
        characters to the right of the center of the screen will be lost.  The
        cursor remains over the same character position, unless it would be to
        the right of the right margin, in which case it is moved to the right
        margin.


DECDWL  Double Width Line (DEC Private)

        <ESC>#6

        This causes the line that contains the cursor to become double-width
        single height.  If the line was single width, all characters ro the
        right of the center of the screen will be lost.  The cursor remains
        over the same character position, unless it would be to the right of
        the right margin, in which case it is moved to the right margin.


DECID   Identify Terminal (DEC Private)

        <ESC>Z

        This sequence causes the same response as the DA sequence.  This
        sequence will not be supported in future models.


DECINLM Interlace Mode (DEC Private)

        This is a private parameter to the RM and SM control sequences.  The
        reset state (non-interlace) causes the video processor to display 240
        scan lines per frame.  The set state causes the video processor to
        display 480 scan lines per screen.  See MODES, RM, and SM.


DECKPAM Keypad Application Mode (DEC Private)

        <ESC>=

        The auxiliary keypad keys will transmit control sequences.


DECKPNM Keypad Numeric Mode (DEC Private)

        <ESC> >

        The auxiliary keypad keys will send ASCII codes corresponding to the

DECLL   Load LEDs (DEC Private)

        <ESC>[ {Ps} q                           Default Value: 0

        Load the four programmable LEDs on the keyboard according to the
        prameter(s).

                Parameter       Meaning
                -----------------------
                    0           Clear All LEDs
                    1           Light L1
                    2           Light L2
                    3           Light L3
                    4           Light L4


DECOM   Origin Mode (DEC Private)

        This is a private parameter to SM and RM control sequences.  The reset
        state causes the origin (or home position) to be the upper left
        character position of the screen.  Line and column numbers are,
        therefore, independent of current margin settings.  The cursor may be
        positioned outside the margins with a cursor position (CUP) or
        horizontal and vertical position (HVP) control.

        The set state causes the origin to be at the upper left character
        position within the current margins.  Line and column numbers are,
        therefore, relative to the current margin settings.  The cursor cannot
        be positioned outside of the margins.

        The cursor is moved to the new home position when this mode is set or
        reset.  Lines and columns are numbered consecutively, with the origin
        being line 1, column 1.


DECRC   Restore Cursor (DEC Private)

        <ESC>8

        This sequence causes the previously saved cursor position, graphic
        rendition, and character set to be restored.


DECREPTPARM     Report Terminal Parameters      VT100 to Host

        <ESC>[ {sol} ; {par} ; {nbits} ; {xspd} ; {rspd} ; {cmul} ; {flags} x

        This sequence is generated by the VT100 to notify the host of the
        status of selected terminal parameters.  The status sequence may be
        sent when requested by the host (via DECREQTPARM) or at the terminal's
        discretion.  On power up or reset, the VT100 is inhibited from sending
        unsolicited reports.

        The meanings of the sequence paramters are:

        Parameter       Value   Meaning
        ------------------------------------------------------------------
          {sol}           1     This message is a report.

        {cmul}            1     The bit rate multiplier is 16

        {flags}        0-15     This value communicates the four switch values
                                in block 5 of SET-UP B, which are only visible
                                to the user when an STP option is installed.


DECREQTPARM     Request Terminal Parameters

        <ESC>[ {Ps} x

        The host sends this sequence to request the VT100 to send a DECREPTPARM
        sequence back.  {Ps} can be either 0 or 1.  If 0, the terminal will be
        allowed to send unsolicited DECREPTPARMs.  These reports will be
        generated each time the terminal exits the SET-UP mode.  If {Ps} is 1,
        then the terminal will only generate DECREPTPARMs in response to a
        request.


DECSC   Save Cursor (DEC Private)

        <ESC>7

        Causes the cursor position, graphic rendition, and character set to be
        saved.  (See DECRC)


DECSCLM Scrolling Mode (DEC Private)

        This is a private parameter to RM and SM control sequences.  The reset
        state causes scrolls to "jump" instantaneuously one line at a time.
        The set state causes the scrolls to be "smooth", and scrolls at a
        maximum rate of siz lines/sec.  See MODES, RM, and SM.


DECSCNM Screen Mode (DEC Private)

        This is a private parameter to RM and SM control sequences.  The reset
        state causes the screen to be black with white characters; the set
        state causes the screen to be white with black characters.  See MODES,
        RM, and SM.

<<<<This one works...and is very handy! >>>>
DECSTBM Set Top and Bottom Margins (DEC Private)

        <ESC>[ {Pn} ; {Pn} r                    Default Values: See Below

        This sequence sets the top and bottom margins to define the scrolling
        region.  The first parameter is the line number of the first line in
        the scrolling region; the second parameter is the line number of the
        bottom line of the scrolling region.  Default is the entire screen (no
        margins).  The minimum region allowed is two lines, i.e., the top line
        must be less than the bottom.  The cursor is placed in the home
        position (See DECOM).


DECSWL  Single-width Line (DEC Private)

        <ESC>#5

        This causes the line which contains the cursor to become single-width,
        single-height.  The cursor remains on the same character position.
        This is the default condition for all new lines on the screen.


DECTST  Invoke Confidence Test

        <ESC>[ 2 ; {Ps} y

        Ps is the parameter indicating the test to be done.  It is computed by
        taking the weight indicated for each desired test and adding them
        together.  If Ps is 0, no test is performed but the VT100 is reset.

        Test                                                    Weight
        --------------------------------------------------------------
        POST (ROM checksum, RAM NVR, keyboardm and AVO)           1
        Data Loop Back (Loopback connector required)              2
        EIA Modem Control Test (Loopback connector req.)          4
        Repeat Testing until failure                              8


DSR     Device Status Report            Host to VT100 & VT100 to Host

        <ESC>[ {Ps} n

        Requests and reports the general status of the VT100 according to the
        following parameters:

        Parameter       Meaning
        ---------------------------------------------------------------
           0            Response from VT100 - Ready, no faults detected
           3            Response from VT100 - Malfunction Detected
           5            Command from host - Report Status (using a DSR control
                        sequence)
           6            Command from host - Report Active Position (using a CPR
                        sequence)

        DSR with a parameter of 0 or 3 is always sent as a response to a
        requesting DSR with a parameter of 5.


ED      Erase in Display

        <ESC>[ {Ps} J                                   Default: 0

        This sequence erases some or all of the characters in the display
        according to the parameter.  Any complete line erased by this sequence
        will return that line to single width mode.  Editor Function.

        Parameter       Meaning
        ----------------------------------------------------------------
            0           Erase from the cursor to the end of the screen.
            1           Erase from the start of the screen to the cursor.
            2           Erase the entire screen.


EL      Erase in Line

        <ESC>[ {Ps} K                                   Default: 0

        Erases some or all characters in the active line, according to the
        parameter.  Editor Function.

        Parameter       Meaning
        ---------------------------------------------------------------
            0           Erase from cursor to the end of the line.
            1           Erase from the start of the line to the cursor.
            2           Erase the entire line.


HTS     Horizontal Tab Set

        <ESC>H

        Set a tab stop at the current cursor position.  Format Effector.


HVP     Horizontal and Vertical Position

        <ESC>[ {Pn} ; {Pn} f

        Moves the cursor to the position specified by the parameters.  The
        first parameter specifies the line, and the second specifies the
        column.  A parameter of 0 or 1 causes the active position to move to
        the first line or column in the display.  In the VT100, this control
        behaves identically with it's editor counterpart, CUP.  The numbering
        of hte lines depends upon the state of the Origin Mode (DECOM).  Format
        Effector.


IND     Index

        <ESC>D

        This sequence causes the cursor to move downward one line without
        changing the column.  If the cursor is at the bottom margin, a scroll
        up is performed.  Format Effector.


LNM     Line Feed/New Line Mode

        This is a parameter to SM and RM control sequences.  The reset state
        causes the interpretation of the <LF> character to imply only vertical
        movement of the cursor and causes the RETURN key to send the single
        code <CR>.  The set state causes the <LF> character to imply movement
        to the first position of the following line, and causes the RETURN key
        to send the code pair <CR><LF>.  This is the New Line option.

        This mode does not affect the Index (IND) or the next line (NEL) format
        effectors.


MODES   The Following is a list of VT100 modes which may be changed with Set
        Mode (SM) and Reset Mode (RM) controls.

NEL     Next Line

        <ESC>E

        This cuases the cursor to move to the first position of the next line
        down.  If the cursor is on the bottom line, a scroll is performed.
        Format Effector.


RI      Reverse Index

        <ESC>M

        Move the cursor up one line without changing columns.  If the cursor is
        on the top line, a scroll down is performed.


RIS     Reset to Initial State

        <ESC>c

        Resets the VT100 to the state is has upon power up.  This also causes
        the execution of the POST and signal INT H to be asserted briefly.


RM      Reset Mode

        <ESC>[ {Ps} ; {Ps} l

        Resets one or more VT100 modes as specified by each selective parameter
        in the parameter string.  Each mode to be reset is specified by a
        separate parameter.  See MODES and SM.


SCS     Select Character Set

        The appropriate D0 and G1 character sets are designated from one of the
        five possible sets.  The G0 and G1 sets are invokedd by the characters
        <SI> and <SO>, respectively.

        G0 Sets         G1 Sets
        Sequence        Sequence        Meaning
        ------------------------------------------------------------------
        <ESC>(A         <ESC>)A         United Kingdom Set
        <ESC>(B         <ESC>)B         ASCII Set
        <ESC>(0         <ESC>)0         Special Graphics
        <ESC>(1         <ESC>)1         Alternate Character ROM

                                        Special Graphics

        The United Kingdom and ASCII sets conform to the "ISO international
        register of character sets to be used with escape sequences".  The
        other sets are private character sets.  Special graphics means that the
        graphic characters fpr the codes 0137 to 0176 are replaced with other
        characters.  The specified character set will be used until another SCS
        is recieved.


SGR     Select Graphic Rendition

        <ESC>[ {Ps} ; {Ps} m

        Invoke the graphic rendition specified by the parameter(s).  All
        following characters transmitted to the VT100 are rendered according to
        the parameter(s) until the next aoccurrence of an SGR.  Format
        Effector.

        Parameter       Meaning
        ---------------------------------------------------------------
            0           Attributes Off
            1           Bold or increased intensity
            4           Underscore
            5           Blink
            7           Negative (reverse) image

        All other parameter values are ignored.

        Without the Advanced Video Option, only one type of character attribute
        is possible, as determined by the cursor selection; in that case
        specifying either underscore or reverse will activate the currently
        selected attribute.


SM      Set Mode

        <ESC> {Ps} ; {Ps} h

        Causes one or more modes to be set within the VT100 as specified by
        each selective parameter string.  Each mode to be set is specified by a
        seperate parameter.  A mode is considered set until it is reset by a
        Reset Mode (RM) control sequence.  See RM and MODES.


TBC     Tabulation Clear

        <ESC>[ {Ps} g

        If the parameter is missing or 0, this will clear the tab stop at the
        cursor's position.  If it is 3, this will clear all of the tab stops.
        Any other parameter is ignored.  Format Effector.
