| I think I understand it!
Speed buffering allows you to have different baud rate between your
modem and your terminal than your modem and the phone line. For
example: You could set the speed of your serial port to be whatever
you like and the modem can still work at 1200 or 2400 baud. That's
really convenient, especially if you share the serial port between
the modem an a faster printer. Without speed buffering your serial
port would have to be set to the baud rate of the modem.
Another application - Let's say you set both your serial port and modem
at 2400 baud and your happily computing. All of a sudden the line
becomes noisy and the Scholars drop to 1200. Rate buffering allows
this to happen and maintain your connection.
The downer is that the speed buffering works (I think) by sending x-on
x-off's which puts the screws to XMODEM. I can no longer use XMODEM
when dialing in through our LAT and it seems it's because all of
the modems have speed buffering enabled. I now use ZMODEM exclusively
because of this. ZMODEM is excellent, too bad handshake doesn't
support it. Although AZComm supports ZMODEM, I think it's the pits
and bought ATALK III which I now use for a Comm pkg.
Hope this helps (and is accurate).
