[comp.sys.apollo] help with modem cables

Does anyone have the correct specs for a modem cable
which will work with /etc/getty? We have a Racal-Vadic
PA2400 modem which was working under SR9.7 with siologin.
If I try to dial into the modem with the node running
SR10.2 and /etc/getty, the phone rings once, the modem
seems to pick up the line (no carrier tone), and then
it seems to hangup! I have tried using both /dev/tty01
and /dev/sio1 without success; but if I kill getty and
run /com/emt on the line the modem will answer the phone,
give a carrier, and connect to the modem which I dialed
in from. Our current modem cable was made back in the
dark ages (SR8.0), and my guess is that getty doesn't
like it.
