I need to setup dedicated 2 way sms server, i use pcmcia sierra aircard 875 (it is voice support),

HOW can i automatically reject the incoming voice call?

As the server is only for handling SMS, not voice.

The modem generates RING (monitored with hyperterminal) when called.

With AT command, it is simple "AT H" to reject incoming voice call (or "AT A" to answer then "AT H" to disconnect).

But i cant access the modem port to create application that do the voice rejection when NowSMS is active.

Any idea?
Or maybe this is a feature request (custom AT Command on specified event/action).

It generally works best to avoid having any calls directed to the modem at all. We've experimented with the type of handling that you describe but with quite a few modems, if the RING comes in in the middle of another command, sending the ATH while another command is pending can leave the modem in an unstable state.

The best solution seems to be to configure call forwarding on the line, forwarding to an invalid number, if possible.
