The answer is to look to the maker of Hotfax and see what modems they support. Don't guess.
I recently migrated to XP from Win98. My fax/answering machine stopped working, so I bought HotFax version 5.0, thinking that my old fax program was not XP compatable. HotFax didn't work. Further checking led to my modem (Gateway softmodem), which could not be upgraded to XP. Time for a new modem.
I suppose it is best to get a controller-based version, but since I have HotFax, I don't think I need to spent $100+ to get a faxmodem. I want to utilize the answering machine feature in HotFax, so the modem needs to support voice also. (Probably all do that anyway.)
Does anyone have a recommendation for a good, inexpensive modem that will work well with HotFax?
