================================== I have a desk-top micro running UN*X 5.0. I also have a digital phone with data connection (System 85). I want uucp (et.al.) to be able to dial out. To get the phone's (switch's) attention, one must send a break signal. Question: how does one get the (acu?) software (names, please) to generate the break signal to get the switch's attention. Incidentally, once the connection is made, the break signal is passed thru unchanged, i.e., the phone system becomes transparent to breaks. A corollary question involves the hangup procedure. To hang up, the DTE (computer) must diddle one of the RS-232 lines, probably the DTE ready line. The switch then disconnects. Question: how does an application level program signal to UN*X or the driver or whatever s/w in the loop that the appropriate RS-232 line is to be diddled? Close the device/file? At this point I don't know which line it is, but a little experimentation will quickly tell (I do know that pulling the plug causes the disconnect). I really don't want to hear that I have to write a special device driver. :-) David Custer AT&T-ISL, Denver, 30F103 (303) 538-3517 druky!ddc
