***Does anyone know how to configure the Sun 3/80 to solve this problem?***
The Problem:
------------
How do I configure a Sun 3/80 running SunOS 4.0 to communicate via a modem
to an HP9000/850 running HP-UX A.B3.10. The HP computer is a timeshare
that I cannot touch. The Sun 3/80 can be configured as necessary.
The modem is a Robotics Courier 2400.
What I've already tried:
------------------------
The modem is already set up and working for Sun-to-Sun communication. I
tried to add the HP host by putting its hostname in the /etc/remote file
on the Sun 3/80 then using tip to the HP host (as for Sun-to-Sun dialup).
The call was placed and picked up but the remote prompt was unreadable
(control characters embedded, no words). Then the session hung. Even
after I powered off then back on the modem, the session remained hung.
Subsequent attempts to dialup with "tip <hostname>" resulted in the error:
all ports are busy.
What the HP expects:
--------------------
The HP host expects the following point to point datacomm configuration:
2400 or 1200 baud
asterisk off
recv pace none
Xmit pace none
parity/data bits none/8
chk parity no
enq ack yes
sr(ch) lo
cs(cb) xmit no
