Cobalt Qube 3 Dail-up and modem trouble

I have a problem that I could not find any help on.

I am trying to use a Dynalink ISDN TA with a cobalt Qube 3 and it doesn’t want to initialise the modem. It works with a normal Creative Blaster 56K but not with the ISDN…any help?

The otherthing is I want to get the qube to dial and go fetch and send mail went it has to, and then to disconnect the line when it is idle, how can I get it to do this?

Thanks

Henri
