        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!
