Sorry for the delay, but I wanted to give it a try before summarizing...
Some people said I should get one of these nice modems which do
calling-back in hardware. Because _I_already_have_a_modem_ (and
not such a beast), that was of no help.
I got a hint to use modempool by Lars Berntzon, too. The uuencoded
file that was included into that mail was not the actual version,
but I had a look at it and found that I will need at least two modems
to have a free line to call back (did I understand it right ?).
Large package, many whistles and bells for my purpose, I think...
Steve Beaty offered a short C program acting as getty login replacement.
I was tweaking this heavily, but had no success until now.
So the best solution would be : drop the available modem and get
an intelligent one (in fact, I could use the `old' thingy at home :/ )
or get into the logic of init/getty/login and write something yourself :(
Another way, avoiding getty, would be polling the serial port in question,
waiting for an incoming call, grabbing the line, asking for identification
(very similar to Steve's solution, BTW) and then hanging up, to call
again and spawn a getty to the already connected line...
Any hints ?
Thank you, whoever responded (or will respond).
