OK, I'm NOT in Tech support but I do use our SCO 386 Xenix
system which happens to use our 8 port products, amongst others.
First, enable the modem control port, say ttyA01, in /etc/ttys.
this should allow dialins.
Second, edit /usr/lib/uucp/Devices to define the modem control
device for each modem say:
ACU ttyA01 - 2400 mt \D
Third, set up a proper dialer script in /usr/lib/uucp/Dailers. Say:
mt =,-, "" \r\pAT&e0\r\c OK ATDT\T\r\c CONNECT
NOTE: This is for a MultiTech V32 modem, your script should do
the right thing for your particular modem.
Add an entry similar to the below to the /usr/lib/uucp/Systems file:
biggie Any,10 ACU 2400 1234567 in:--in:--in: feedme sword: lotsOnews
Now you should be able to cu or uucp to biggie on ttyA01.
Logins on ttyA01 should work as well. I've dialed in and out of our
system many times a day with a setup like above, it SHOULD work for
you too. The above should also work on our concentrator line as well.
Also, you should check your modem's setup VERY carefully to make sure
all it's registers are set up properly. I know I had to putts with
my Telebit T2500 for a while before I could get it to do the right
thing.
If your modem is capable of doing it, you should set
the computer<->modem baud rate to the highest the modem can handle
and tell the modem to use hardware flow control. This will give
you the best throughput possible no matter what baud rate the person
calls in at or you dial out at. Please note that you should set up
your modem to autobaud on the incomming phone line but lock the
computer<->modem interface at high speed.
Finally, check to make sure the cable between the computer and
modem is wired correctly for modem control signals.
If you have any more problems, call Tech Support. That's why we have
them, to help out our customers.
