You can only use Procomm on a pc running windows. I use my laptop with a usb bluetooth adapter to connect to my phone's modem. After installing the bluetooth adapter, you need to pair up your phone with your pc. Then you can setup the bluetooth services that your phone supports like handsfree, fax, modem, file sharing... Once you have the modem feature setup, you can select procomm to use the bluetooth modem to dialup to your remote site. Unless you have a terminal emulator on your handheld (palm,pocketpc), you can probably use it to dial directly, otherwise you need a pc to do the termial emulation, and your phone with a bluetooth modem.
