I want to use the program "ct" from the UUCP package for interactive callbacks. If I call a UNIX-host from my UNIX-PC with a modem and "cu" to order "ct" on the host to call back my PC, then: 1. In which state are the PC and the modem, when the host forces its first hangup to get the line free for the callback? I think I have to stay in the cu session (in dial-out mode) and wait for the dial-in of the callback. What about the handling of the control lines, especially DCT ? 2. In BNU: Can ct be a "service" in /usr/lib/uucp/Sysfile like cu or uucico - if it were neccessary to give a special initialization of the modem for ct in /usr/lib/uucp/Dialers ? How good is ct integrated in the UUCP package (BNU) ? Who has worked with ct and can give me some hints ? Thank you very much! Toni Greil, Muenchen Germany

Wish I could be more help on this one... All I can tell you here is that
your UNIX-PC must be sitting there like a terminal with a modem on it, ready
to answer the phone when it rings, and go into a data mode..

The only other problem I've had with "ct" is it appears as though you can NOT
run a uugetty on the "out-bound" port of the computer that is CALLING you.
The outbound port should be just that, outbound only.. Running a uugetty on
this port will do STRANGE things, like drop the session shortly after you
connect and hit a few returns..
With no getty, your phone should ring, you answer, the modems connect, hit
return a few times and you should see a login message!

It's because _c_t spawns a normal _g_e_t_t_y (which in turn starts _l_o_g_i_n), and _g_e_t_t_y doesn't understand the locking mechanism used by _u_u_g_e_t_t_y and _c_u to control access to the serial port. It's a known problem, but I don't think anyone's done anything about it..
