newby wants to monitor serial port or ISDN

[twillert]

I came acors Girder when looking for a means of ready a level into a PC (running w2kADV server).
I want to monitor an extern device receiving telelephone calls
If a certain number is called, a relya is closed and a contact can be read by a serial control line.
This signal should then activate a computer restart.
If it is possible to get such signals from a ISDN line it would be even the better.

I do not know exactly if Girder is the right instrument to do such things.
Who wants to send me a "quicky" to get me going

Thanks Herman
