I used to have an AST Advantage 14.4 Fax/Data/Voice modem. I found out
It (mine) emulates a Hayes Ultra Smartmodem. Did yours come with an AST
computer? If it did, then look  in the AST help files. I think it's on
the right side of the screen on the AST shell, "Ask AST". I found a
listing of ALL the commands and a brief description of what they do/what
they're for.
If you don't have an AST computer, I can send the commands to you as a
text file, or I *think* I can send the actual help file. It reads like a
normal MS help file.....
Hope this helps....

assistant: MIKE FARRILL wrote in a message to RICK COLLINS:
It reduces the overhead by stripping the start/stop bits however the data is
sent in packets with their associated overhead (7 bytes per packet in most
implementations).  That is, without using EC, you modem needs 10 bits for
each character sent so a 33,600 connect would have a maximum throughput of
3360CPS.  Using EC and stripping the start/stop bits gives a theoretical
maximum of 33600/8 or 4200CPS.  However, we now have to allow for the
overhead which means the calculation (using a 128 byte packet) becomes:
33600/8 * 128/135 * 60/61 or 3617CPS.
          ^^^^^^^|  ^^^^^___a zero bit is inserted approx. every 60 bits
                 |
                 |___packet size divided by (packet size plus overhead)
28800?  With error correction, 28800/8 or 3600CPS.  Using a 128 byte packet,
3357CPS.  A 244 byte packet increases this to 3442CPS and a 256 byte packet
(MNP 4 for instance) increases this to 3447CPS.  In theory, you can use
larger packets however I haven't used a modem that went over 256
tes/packet.
Ymodem-g will allow you to come closer to that theoretical maximum -- you
just can't exceed it with incompressible data.

Write your reply.

assistant: Nope.  It increases the throughput by using fewer bits (8 rather than
10) to represent a character.  The bits are sent at exactly the same
speed with or without EC.
28800/8 less overhead.  About 3400 cps or so.
Sure.  But it _can't_ improve the number of bits the modem can handle
in a second, can it?  It improves throughput by eliminating the
ZModem overhead - at the expense of Zmodem's error detection and
recovery.  If you get a CRC error with YModem the transfer is
terminated.

assistant: I don't know if this is the most appropriate echo for this question,

I run a two line BBS system here that I've had online for about 7 years
now, and I run two 33.6 USR Sportster modems on it.
I've been having some intermittent line noise problems here and have
had the phone company check the lines, with no luck.  Mostly what I
notice here is people across certain local prefixes have more problems
than callers from other prefixes, with line noise.
My question here is:  Is there some device I can use to condition my
lines and/or alter the db level to improve upon the lags and loss of
carrier my callers are getting?  Is there something I can have the
phone company do with the db level that would help?   Or would they
even do it for residential phone lines?
Any help would be most appreciated.

Write your reply.

assistant: Well, 56K or X2 technology is simply looking liks this...
 ISP/BBS===DIGITAL PHONE LINE===>Teleco===>ANALOG PHONE LINE===>YOU.
 X2 technology uses the fact that most ISP and some BBS uses digital phone
 line (T-1, ISDN, etc), and since the conversion is only one way (Digital
 to Analog), they can cram more data into the signal without fearing for
 data loss due to the ADC sampling (Quantizition (sp?) error I believe).
 Since this technology requires one side to have DIGITAL phone line, it
 also restricts that only the "Server" (ie:ISP, BBS, or whoever have a
 digital phone line) can send at 53.3Kbps (current limit imposed by teleco
 equiptment, USR is peitioning for FCC to increase to 56Kbps), but the
 "client" (whoever uses the Analog end of the connection) can only send at
 a maxinum of 33.6Kbps...
 I hope this clears thing up...
