This has two noticable ramifications: 1) Depending on the c_feedback settings of /dev/ph?, if there is an active call, you may hear the actual sound from phone line (i.e. "modem squawk"). This is probably what you heard. It only seems to happen at certain times; I think it is when an incomming uucp call is in progress. 2) When the phone is actually being dialed, the dialer is not available for "beeping." At these times, beeping does not occur. -- Mike Ditto -=] Ford [=- P.O. Box 1721 ford%kenobi@crash.CTS.COM Bonita, CA 92002 ford@crash.CTS.COM
