Flow control with my modem.

[seane@pro-scat.cts.com (Sean Eller)]

Hi all, I've got a supramodem 2400plus and I've been unsuccessful so far
with the v.42bis compression when sending large amounts of data.  Actually
it works fine in proterm because it keeps up with incoming chars, but I've
been using a desktop nda term program which strictly uses the control panel
settings and it seems that it can't keep up.  I've got a rom 3 with 6 meg,
a zip 10/64 and a bunch of background crap going like pointless, express,
harmonie, The Manager, etc. so I know the processors bogged down with all
the stuff going on.  I set my control panel to dcd handshake on, dtr
handshake on, xon/xoff on, buffering on, echo off, add lf off, delete lf
off.  From looking in the supra manual I figured the problem was that chars
would come in too fast into my gs's buffer before it could be cleared and
there'd be an overflow sent to the sending modem causing it to drop
carrier.  I don't know for sure but when the buffer does get backed up this
is what happens.  The modem drops carrier in the middle of an ascii dump at
9600 throughput(v.42bis).  So, ny idea was that the modem with it's \q1
setting would allow xon/xoff for the serial port and with the serial port
set to send an xon/xoff that when the buffer got full it would allow time
for the computer to catch up and not cause an overflow.  However, this idea
has failed.  So I don't have any idea why this thing is still dropping
carrier after a little while of an ascii dump.  Does anybody know what's
going on?  Thanks....
