Hanging up modem after 30 minutes (TSR?)

I have dial-up internet connection and
I would like to know how can I hang up my modem
after I have been online 30 minutes (or 120 minutes or
what ever time I choose).

It would hang up modem when duration in Windows 95
dialer is 00:30:00 and redial immediately after that.
And again hang up after 30 minutes and redial (loop :)
So the program would start after I have connected
(like ICQ does).
 
I guess I need some kind of tsr, but how do I do it?
Give me so advice where to start. I can use Delphi 2 or 3.

BTW Sorry bad english

I'm not sure I understood the question, however it appears as
this could be a perfect case for a TTimer that would check the
time elapsed (or Dialer duration) every 30 minutes or so and take some action (Dial again or hangup the modem).

ToniTop,
You do not need a TSR for this activity but rather a small Delphi program to get the list of running tasks (Dial Up Networking in this case) and it's associated window handle.

Once you've determined the handle of the "Dial Up Networking" application, check it's child windows until you come to the label containing the "On-line" time. It's this label your program will monitor.

Once the label (minutes portion) reaches 30 then issue a WM_Click message to the "Disconnect" button on the form to close the connection. Wait about 10 seconds and issue a WM_Click message to the "Connect" button on the form. This will connect and re-set the on-line timer where you program will wait for the minutes to reach "30" again, thereby repeating the cycle. Hope this helps.
