Hi Adam,
My computer is hooked to the net by cable modem but it also has a 56K modem I use sometimes to send faxes. I have often programmed my fax software to send faxes while I am doing other things on the web. I don't understand why you can't do this too, unless your computer no longer has a modem. Sending faxes doesn't require a TCP/IP connection. And you computer is capable of multi-tasking. It runs independent of your internet connection. I must be missing something. I don't see the problem.
Best Regards, Steve MacLellan
