csend
This application uses low-level, noninfopkt, raw-data, fax-sending
routines to send facsimiles. It allows sending a single fax page either
in standard fax format from an MH/MSB G3 data file or in an
enhanced fax format (e.g. JPEG, JBIG) from an EFF data file. T.30
holdup is used to check on the receiver's capabilities before deciding
which type of file to send.
Turn on the Bfv API debug program from the command line. The
btcall.cfg file is the configuration file. The csend program is found in
the app.src directory.
