ArcFax was the first fax modem program for RISC OS. It allows you to use almost all fax modems for sending and receiving faxes on all RISC OS hardware. Faxes are generated by printing, so anything you can print, you can fax.

The latest version of ArcFax has been extended into an integrated fax, voice and data modem program. ArcFax can use the new Class 8 modems to act as an answering machine, and can use almost any modem for transferring files in an easy way.
