Enumerate Installed Modems with Port numbers

Hi

I know how to check for modems using MSComm control. I send ATI1 and ATI3 commands to ports one by one. If port returns "OK" in the input buffer then its a modem. But this method FAILS if a port is already in use/open, for example,if allready used by dial up internet connectivity. Is there any other way of finding modems? Like finding from registry or some API.

Thanks in advance :)

This will display info on installed modems.

Thanks for modem.zip.

But it doesnt seem to work at all.

Isnt there any other way, other than to use WMI.

Thanks for your kind reply :)

Is there nobody who can help me?
