efax is a small ANSI C/POSIX program that sends and receives faxes using any fax modem (Class 1, 2 or 2.0).
efax is smaller and easier to install than HylaFAX or mgetty+sendfax. As one user put it ``EFAX is a nice simple program for single user systems.''
The ``fax'' command, a shell script, lets you send, receive, view and print faxes. In larger systems, faxes can be sent by printing to a ``fax'' printer and received faxes can be e-mailed as MIME attachments to an administrator for distribution. efax can also pass incoming data calls to a getty program.
The efax package includes ``efix,'' a program to convert between various image file formats. To fax Postscript files you will need Ghostscript. To view faxes you can use any program tha displays PGM files (e.g. xloadimage or xv). efix can also convert received files to Postscript or HP Laserjet formats for printing.
Version 0.9 of the program was written and tested under Linux 2.0. Previous versions have been compiled and used under most versions of Unix and should work with minor changes on any UNIX with an ANSI C compiler and libraries that include select(2) and termios(4).
