Thank you very much for your reply.  BTW...glad to see your firm making
a comeback.  I have one of your early 300 baud products in my attic.  Is
your BBS still working and what's the number?
Always use ZMODEM and 19.2 on my COM port (run errors with "some" boards
if I go higher). My UART is a 8250 according to MSD.EXE. Operating in
DOS using DOS comm package Telemate v.4.20 (registered ).  I use a
386SX/25 e/w co-processor.  Regularly connect to 6/7 local and several
800 BBS numbers. Typically DL *.zip files. Do experience higher thru-put
when DL/UL text files but I understand why.  Live in a residential area
supported by Bell Atlantic's eletronic switching capability.  There's
loads of fiber throughout this area.  Do not 'hear' ground hum (60Hz),
white noise or crosstalk on my telephone line. People I speak with via
telephone do not complain of hearing anything either (except sometimes
me ). However, I do have many extention telephone jacks throughout my
house. About 1/3 of them do not have telephones connected to them.
With that as a backdrop, I typically achieve only 1300-1500 CPS.  The
mid 1400s is very common for me.  After reading your reply I think I'll
try some house wiring elimination work.  I'll start by disconnecting all
unused extension wiring and go on from there. Perhaps there is some
filtering going on that is affecting my thruput.  I dread the thought of
trying to talk to Bell Atlantic about a modem thruput problem.
