Write your reply.

assistant: rite
ow
The FPU won't let you store data into the CPU registers or load data from the
CPU registers, but other than that, your ASM proc can't tell one data type
from another unless you tell it to.  Take the following two instructions for
example:
        FILD    DWORD PTR [BX]
        FLD     DWORD PTR [BX]
They both load from the same memory location, pointed to by BX, but the first
one loads it as an integer, and the second as an IEEE single-precision real.
If you're using a good assembler with a MODEL and declared your function as a
PROC in assembly, you can use something like this:
        LOCAL   varname:type
you can list several on one line, separated by commas.  "varname" is the name
of your variable, and "type" is a specifier telling it how much stack space
o
allocate for it (BYTE, WORD, DWORD, QWORD, TBYTE, ...)
If you aren't using PROC statements, then here's the standard entry code for
most high level languages:
8086 code:
        PUSH    BP
        MOV     BP, SP
        SUB     SP, LocalSpace
80186+ code:
        ENTER   LocalSpace, 0   ; single instruction to do all of the above
Where LocalSpace is the total amount of space you need for your local
variables.  When I have my C compiler generated mixed code, it generates
comments showing what the stack offset for each variable is, and you'd access
them as [BP+disp] or [BP-disp], if they were parameters or local variables,
respectively.
Here's the standard exit code:
8086 code:
        MOV     SP, BP
        POP     BP
        RETF    Params
80186+ code:
        LEAVE   ; no operand needed, does the same as the first two above
        RETF    Params

assistant: Sorry, I was only joking. <G>
    Ahhh, I see. Right. I need to access the DSP chip on my modem. But
the major problem is that I need the spec. of the board, which I will try
to get from the developers if possible. The idea is that I would like to
make a Dos driver for the modem. To do this I would need to know how
one would normally access a serial port down to the IN's & OUT's and
How I would be able to emulate a serial port. Processing the questions
and outputting the answers, as if a 16550 Fifo.
    No-one seems to have done the above yet, so I would like to do
it myself.
    Until I get the spec. for the DSP board, I cannot do much in that
direction, but I still need to know about serial access's to 16550's.
    O.k. So Assuming I have a standard serial port. How would I
send information to the modem, say, an AT command? How do
set the modem up, open the port, etc.. I have read the part of
Ralph Brown's Interrupt list about ports, but I soon lost the
plot. Do I need to get hold of a technical specification of the chip?
Thanks..

To answer your question.  Yes, GOTO always compiles to JMP.  Don't
think of JMP as the Achilles Heal of assembly, as GOTO is considered
the Achilles Heal of BASIC.  Instead use both only when you need them.

Write your reply.

assistant: A bit of an expansion on what you're saying there ... in order to keep the
highest possible framerate with objects/effects moving at the same speed
(realtime):
1 - reprogram the timer 2 - hook the timer ISR with a routine that maintains
a position table for each object.
3 - have the main program update the screen depending on the contents of the
table maintained by the PIT ISR
 The only aspect of this method you really have to worry about is that you
take a copy of the position table (while CLI'd) before you start to update
the screen, otherwise race conditions could lead to some very interesting
effects on slow machines (objects being in several places at once and so
forth).
