IntroductionThis is the README file for version 0.7a of efax, a program tosend and receive faxes using any Class 1 or Class 2 fax modem.efax is a relatively small ANSI C/POSIX program that provides thedata transport function for fax applications.  A simple shellscript (``fax'') is included in the distribution to let youcreate, send, receive, view and print faxes.efax is smaller and easier to install than FlexFax, NetFax, ormgetty+sendfax.  It uses your system's own getty to handleincoming data calls. As one user put it, ``EFAX is a nice simpleprogram for single user systems.''The package now includes the ``efix'' program to convert text,fax or PBM files into fax, PBM, PGM, HP-PCL or Postscript files.To fax Postscript images you will need Ghostscript.  To previewfaxes you will need a PGM file viewer (e.g. xv or xloadimage).If you don't have a PCL or Postscript printer you will need anappropriate conversion program (e.g. pbmtoepson or Ghostscript) .This version of the program was written & tested under Linux0.99.14.  Previous versions have been compiled and used under AIX3.2.4, BSD, HP-UX, IRIX 5.2, NeXT, OSF/1V1.3, Solaris 2.x, SunOS4.1.1/4.1.3, SCO 3.2.0, SysVR4.2, and ULTRIX 4.3 and should workwith minor changes on any modern UNIX with an ANSI C compiler andlibrary including select(2) and termios(4).efax is distributed as a gzip'ed tar file, efax07a.tar.gz.  Itmay be obtained by anonymous FTP from sunsite.unc.edu in/pub/Linux/Incoming or /pub/Linux/apps/comm/fax.	    Changes from version 0.7 to version 0.7a- fixed bug in efix that dropped the last line on each page- fixed bug that caused training check to fail with some modems- added a Makefile	    Changes from version 0.6a to version 0.7- includes the "efix" program to convert between file formats (no  longer requires Ghostscript or PBM utilities)- generates page headers using a built-in or external PBM font- resets START and STOP characters to XON and XOFF (fixes some  flow control problems)- retains modem responses generated during data transmission  (fixes problems with USR Sportsters)- isolates Unix dependencies to simplify porting to other  operating systems- computes accurate timeout for draining modem's transmit buffer- enables "software carrier" if available- many minor bug fixes and improvements			    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 efaxlib.h  - header file for functions common to efax and efix efaxlib.c  - functions common to efax and efix efaxos.h   - header file for OS-dependent functionsefaxos.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 and             print faxes.efaxfont.h - 204x198 dpi 10-point Courier fontefaxfont.l - 204x96  dpi 10-point Courier font			  Installation	Edit the makefile and change the compiler and the destinationdirectories if required.Type "make" to build the efax and efix binaries.  Modify the variables at the beginning of the `fax' shell scriptaccording to the comments.  Type "make install" to install the binaries and man pages.The efax(1) man page has information on resolving problems anddescribes how to modify /etc/inittab (SysV) or /etc/ttytab (BSD)so efax can handle incoming fax and data calls automatically.
