IntroductionThis is the README file for version 0.9 of efax, a small ANSIC/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 ormgetty+sendfax.  As one user put it ``EFAX is a nice simpleprogram for single user systems.''The ``fax'' command, a shell script, lets you send, receive, viewand print faxes.  In larger systems, faxes can be sent byprinting to a ``fax'' printer and received faxes can be e-mailedas MIME attachments to an administrator for distribution.  efaxcan also pass incoming data calls to a getty program.The efax package includes ``efix,'' a program to convert betweenvarious image file formats.  To fax Postscript files you willneed Ghostscript.  To view faxes you can use any program thatdisplays PGM files (e.g. xloadimage or xv).  efix can convertreceived files to Postscript or HP Laserjet formats for printing.This version of the program was written & tested under Linux 2.0.Previous versions have been compiled and used under most versionsof Unix and should work with minor changes on any Unix with anANSI C compiler and libraries that include select(2) andtermios(4).efax is distributed as a gzip'ed tar file, efax-0.9.tar.gz.  Itmay be obtained by anonymous FTP from metalab.unc.edu in/pub/Linux/apps/serialcomm/fax.	    Changes from version 0.8a to version 0.9- fixed bad (0x0 pixel) file output on new glibc systems- fixed bad file output on 64-bit systems- automatic selection of baud rate and class- hardware flow control made optional- modernized directory and file names- many bugs removed, others added			    ManifestThe efax distribution should contain the following files:README         - this fileCOPYING        - the GNU General Public LicenseMakefile       - makefile to make all/install/cleanefax.c         - program to send and receive faxesefix.c         - program to convert between file formats efaxmsg.{h,c}  - functions to print errors, warnings, etcefaxlib.{h,c}  - functions common to efax and efix efaxio.{h,c}   - low-level modem i/o functionsefaxos.{h,c}   - OS-dependent functionsfax.1          - man page for fax(1)efax.1         - man page for efax(1)efix.1         - man page for efix(1)fax            - a (Bourne) shell script to create, send,                  receive, view and print faxes.			  Installation	Edit the makefile and change the compile command and destinationdirectories if required.Type "make" to compile the efax and efix binaries.  Edit the configuration information at the beginning of the``fax'' script according to the comments.Type "make install" to install the fax script, the binaries andthe man pages.Read the fax(1) man page first for information on using efax.The efax(1) man page has details on resolving problems, settingup a network fax server and using efax to handle both fax anddata calls.
