o For technical accuracy.


I am trying to attach a high-speed modem directly to A/UX, but it won't answer
the phone. When I attach to the Macintosh OS and run Kermit, the modem
answers the phone. If I attach it to a Xenix system, it answers the phone.
We've got a MicroCom 9600+ and a MicroCom 2400+. AutoAnswer, Carrier Detect,
and DTR active. Macintosh Plus to RS-232 (not Apple cable).

The MicroCom modem Front Switch settings should be:

Switch 1 : Up Switch 2 : Down Switch 3 : Down Switch 4 : Up
Switch 5 : Up Switch 6 : Up Switch 7 : Up Switch 8 : Up

Rear Switch Settings should be:

Switch 1,2 : Down-Up
Switch 3,4 : Down-Up
Switch 5 : Down
Switch 6 : Up
Switch 7 : Down
