Assuming you mean to use the Telebridge as a NetSerial to connect the
serial Fax modem to the AppleTalk LAN... It is "highly desirable" and
also won't work.  FAX transmission is synchronous (and continous) there
is no handshaking for flow control.  If the fax transmission is
interupted, as can happen on a network, the connection breaks.

Early versions of the LightFax Netmodem (Computer Friends - (503)
626-2291) software spooled the "fax" from the user to an AppleShare or
TOPS file server and then sent the fax from a separate "Fax Server"
Mac.  During transmission the "Fax" server read the fax from the file
server.  The scheme worked well for short one page faxes.  But
inevitably died before page two of longer faxes.  Their new software
copies the fax document in total to the "fax server" from the "file
server" before transmission.
