[comp.dcom.modems] FAX WITH SOFTWARE & USR HST 14.4K ONLY???

gwang@igloo.scum.com (George Wang) (07/19/90)

Is it possible to do standard FAXES (send & receive) with SOFTWARE
only and no special fax hardware.... I have a USR Robotics 14.4K
HST with the new V.42bis mod...

I heard there is a program for MicroSoft Windows 2.X called
Power Page which lets you do this.. Is this true??

Please email responses.. I will post a summary if needed...
I will respond to all email so if you don't hear from me
please post to newsgroup as this machine is not directly
linked to internet...

Thanks in advance!
George

No, it is NOT possible to communicate with fax machines from 
standard PC modems.  The modems you and I most often use have Bell 
103, Bell 212, CCITT V.22, V.22bis, and V.32 modulation schemes, 
with possibly a proprietary scheme thrown in for good measure (Hayes 
ping-pong, USR HST, Telebit multicarrier, etc).  Fax uses other 
modulation schemes:  CCITT V.21, V.27ter, V.29, and soon to be V.17 
for higher speeds.  There is no way to "fake" a modulation scheme in 
software -- your hardware has to support it.  You CAN send your 
faxes through a third party (e.g., Compuserve, MCI Mail, AT&T Mail, 
etc.), but THEY have to have the hardware (fax modems) to 
communicate with the fax machine.
