Do you know if there is other fax software that supports ECM?
Please forgive me for butting in on this thread, but I can't resist plugging HylaFAX.
Almost all fax software, including your WinFax 7.0, that supports Fax Class 2, Class 2.0, or Class 2.1 will usually therefore support ECM when the modem (DCE) itself supports ECM in those Fax Classes. This is because the DCE does the ECM protocol work, and the software (DTE) doesn't really notice the difference. Using Class 2 for faxing you are mostly subject to the mercy of the modem manufacturer for quality, so any bugs must usually be fixed in firmware.
Modems that I know of that support ECM in some fashion in Class 2/2.0/2.1 are the MultiTech 5634 V92 family (MT5634ZBA-V92, ISI5634, etc.), the Digi AccelePort RAS, and the Eicon Diva Server. There probably are a few more, but yes, this is a very short list. Most modems do not support ECM in their Class 2 firmwares.
However, many (although not all, dare I say most?) modems support Fax Class 1 or Class 1.0. In this mode the faxing is heavily dependent upon the DTE and thus the support or lack of support for ECM comes from the fax software. Your average fax software that comes on a CD bundled with your modem is not going to support ECM. Symantec (your WinFax people) recently purchased the rights to Procomm Plus (yes, if you're an old BBSer you may have this on your shelf), which does support ECM in Class 1, so maybe Symantec will get that ECM technology into WinFax eventually. In the open-source world, HylaFAX now supports ECM in its Class 1 implementation in its current CVS HEAD (to someday become 4.2.0).
I don't know of many other Class 1 Fax Softwares that support ECM.
