ttymon Unixware

I can well remember rolling my eyes over sacadm and ttymon. It's not that it is a horrible idea; it's just that it is much different than just running getty on a port in inittab.

The man page for ttymon is the place to start. You might also find Incoming PPP Setup on Unixware 7.x helpful.

This is a repost of an article I managed to post a while ago concerning
a similar issue : 

=== cut here ===

I've been involved in a modem installation under UW 7.1 in the
last few days and, after much fighting, sighing, crying and so on, 
I've been able to get the long awaited login prompt by manually
changing the /etc/saf/ttymon1/_pmtab file (assuming that ttymon1
is the label assigned to your port monitor). As an example, stop
the port monitor (sacadm -k -p ttymon1), switch to /etc/saf/ttymon1
and, by using the editor of your choice, change the _pmtab as
follows :


# VERSION=2
termA1:u::reserved:reserved:login:/dev/term/A1:ohr:0:/usr/bin/shserv:60:
38400_8N:ldterm,ttcompat:login\:
:::::#

Please notice the tenth field of the above string (/usr/bin/shserv); by
default it's automatically set to "auto" and this caused us a log of
headaches. Once replaced with /usr/bin/shserv, everything went as
expected (please change the twelfth field - speed - accordingly to
your needs).

Next restart your port monitor (sacadm -s -p ttymon1) and see what
happens; if you have trouble, please check /var/saf/ttymon1/log for
additional details.

Note: the above workaround was originally posted under this newsgroup
by a wyse guy whose name I can't remember right now - kudos to him
for his knowledge.

The problem you're experiencing could be due to a bad serial cable
wiring too; I had the same problem while trying to connect a serial
terminal to a UW 7.1.0 machine. To get the above to work I had to
phisically wire DTR and DCD on the UW7 side, even if I was logging
in via a null modem device (actually it was /dev/term/00t which,
as stated in the docs, DOES NOT consider modem signals). OK, this
is not your case but consider downloading patch ptf7613a  if
you plan to do the above connection.

Best,
Roberto
