I have a Sun 3/60 running SunOs 4.0, and I'd like to set an incoming autobauding tty line. I made the following entry in /etc/gettytab: M|Modem|Modem-Autobaud:\ :ab:sp#1200: and this entry in /etc/ttytab: ttya "/usr/etc/getty Modem" dialup on secure where ttya is the line I want to autobaud. The problem is that the autobauding doesn't seem to work! The line gets set to 1200 baud regardless of the speed of the modem or terminal connected to it. Do you have any other ideas on how to implement this? Thanks, E.

It is my impression that autobauding on Suns is basically impossible
because the proper lines aren't failsafed and so you see random junk on
the ports often enough to send the autobaud algorithms crazy.
It's been a long time since I dealt with this, but I remember some Sun
3/280s that we had at a previous company that would get CPU bound if we
left long RS232 lines dangling (i.e. not connected to some other box
somewhere). It seems like this can be solved by using appropriate
tie-down resistors or something, but don't ask me for details I'm just a
SW weanie.
