Steve,
HylaFAX supports 1D MH, 2D MR, and 2D MMR.
The last time I looked (a few months ago) it supported those file
formats, but only supported 1D transfers on the wire.
ECM is new in HylaFAX, but already seems more robust than the implementation
one finds in most consumer-grade data+fax modems.
As for the tiny fraction that support ECM... well if tiny fraction means
"damn near most of 'em", then I'd say you're about right. Heck, 30-40% of
them even support V.34 these days (for which ECM and MMR are prerequisites).
Our customer send and recieve hundreds of thousands of faxes daily, and the
great majority of them are ECM error-corrected.
The last time I checked on a big FAX server, only a few percent of the
calls used anything but basic 9600bps non-ECM operation. When I look in
the shops, hardly any of the FAX machines - other than the low selling
high end laser models - support anything fancy. If you are dealing
purely with FAXes between big companies, most of the machines you
encounter probably support the fancy features. In the general case, they
don't.
I'll admit, these numbers are more representative of the US and Europe than
other regions, but still, 'tiny fraction' is underselling it just a wee bit
;-)
Asia is generally ahead of Europe and the US in buying fancy telecoms
kit. However, our much higher penetration of broadband is probably
killing FAX more quickly here. :-)
Regards,
Steve
