- Change wiring to:
-
- W <------Wyse Modem
- a <----Y-Adaptor-<
- l <------PC Modem <----Phone
- l
-
- So that Wyse and PC are in parallel. Original wiring disconnects
- chained device when modem connects.
-
- Commands for receive-only mode are:
-
- AT C0 S10=255 m Where m=O for originate or A for answer
-
- C0 turns off the transmit carrier so the monitoring modem just listens.

-
- That's a different question, to which the answer is also yes, but put
- them in parallel and don't turn off the transmit carrier.
