Message-ID: Date: 20 Sep 90 05:21:25 GMT Sender: news@ucs.adelaide.edu.au Organization: Digital Arts Film and Television Lines: 26 Nntp-Posting-Host: chook.ua.oz.au I have a Personal Iris, with a Hayes compatible modem attached to serial line 2. I have written a program which resets the modem (using ATZ), sets up some parameters, including the hangup-when-DTR-dropped state, then dials up a remote computer, finally establishing an SL/IP connection to it. All works well, using port /dev/ttyd2, except if the remote computer hangs up the line. The sliplogin program on this end does not appear to receive a HANGUP signal. I cannot use /dev/ttym2 because it won't allow itself to be opened until DCD is asserted, and this does not happen until the remote dialup is complete. I can't establish the session with /dev/ttyd2, then close it and open /dev/ttym2, because that would cause my modem to hang up, which I want to happen (this is how the connection is terminated at my end). Have I missed something? How should I be doing this? -jeremy -- -- Jeremy Webber ACSnet: jeremy@chook.ua.oz Digital Arts Film and Television, Internet: jeremy@chook.ua.oz.au 60 Hutt St, Adelaide 5001, Voicenet: +61 8 223 2430 Australia Papernet: +61 8 272 2774 (FAX)
