Modems on Sun 3/80, 3/260 and SPARCstations

[Alan Medsker]

I'm having some trouble getting consistent results when trying to get a
modem off a Sun 3/80 (as well as one off of a 3/260) to be used for
dial-in.  Here's the poop:

Sun 3/80, modem on /dev/ttya, ttytab entry sez:

   ttya    "/usr/etc/getty d19200"         dialin          on remote

and gettytab sez:

   # Put :ms=crtscts,-ixon,-ixoff for binary xfr and emacs 12/28/90 tom
   d19200|Dial-19200:\
           :ms=crtscts,-ixon,-ixoff:nx=d1200:fd#1:sp#19200:

The modem is a Microcom AX/9600 Plus (MNP Class 6).

Symptoms are that garbage greets the person calling in, but not every
time.  I also have a 3/260 with a Multitech V32 modem on /dev/ttya, and I
rebuilt the kernel to allow for this.  It worked for awhile, but on
occasion I get receive and transmit lights on the modem flashing
continuously, apparently forever ('til I reset the modem).

ttytab:

ttya    "/usr/etc/getty d9600"          dialin          on secure

gettytab file isn't clear to me (I don't have a d9600 entry--is this a
prlblem?).  I would also like to do this on a SPARCstation at some point.

I guess what I would *really* like is a one-page summary on how to do
this, in general.  The manuals seem to be antiquated in this particular
area...  If you can email me your replies, I'll post a summary which will
hopefully be what I wanted in the first place.

Thanks in advance!
