Michael,
When you say, "I get the prompt back", does the APC on COM2 actually
*tell* you something? If so, what?
Do you have any old external modem laying around? Even a 2400bps or
slower will do.
If so, connect it to ttys1 (Yes, COM2) and use minicom to talk to it.
Your 'AT' commnad should return 'OK'. So, you have contact with the
outside world through ttys1.
Some (most?) APC units need to have the DIP switches correctly set to be
able to talk to a PowerChute software. (Read the APC manuals.) Have you
been able to run PowerChute to this unit under another OS?
Regards
Gustav
