I was wondering if anyone out there might be able to give me some
help. I purchased a Telebit Trailblazer+ last summer, and installed it on
/dev/tty1A in place of my Hayes modem. I was providing support to a system
almost 200 miles away, using AT&T long distance. I could not get uucico
to run at 9600 or 19200 (after using the new SCO uucico, dialTBIT, and running
dial -z on the modem), but it worked fine at 2400 baud. I brought the modem
and serial card home, installed them into my friends souped IBM 386 running
SCO 2.3.1, and all worked fine. I figured that it was the phone lines.
Now, that I graduated, and moved back home, I expected perfect 19,200
baud connections -- WRONG! Now, I am 5 miles from the site, but can only
get 9600 baud communications, and sometimes these fail too. If I connect
via cu, and cat files, etc., it seems that the modem looses characters some-
times.
If I try to connect via uucico at 19,200, my machine logs in, and
starts processing the first message, but will eventually return a message
like:
FAILED -- expected 'S' got FAIL
or the PGPKT can't read error. I thought I heard a rumor about a fix for
SCO 2.2.x about the RTS/CTS flow control. The 386 system I administer
has this fix installed, and uucico runs fine at 19,200 baud. If anyone
could supply any information that might be of some help, I would be
very grateful. Thanks in advance!

Thanks in advance! There is a patch available from SCO Tech Support xnx105 which addresses RTS/CTS handshaking supplement. Corrects problems using RTS/CTS handshaking. Available on 96tpi,135tpi media. Submitted on 10/01/88. Hope this helps. -- .. Computer Consulting Service .. Bob Willey .. .. P.O. Drawer 1690 .. uunet!consult!bob .. .. Easton, Maryland 21601 ..
