: I have ported netfax, but I can't get it to work.  Everything
: compiles, and runs (well, mostly), but FAX's get aborted during send.
: I get the same problem with two other FAX sending methods, so I think
: there might be a problem with hardware flow control (I'm using

: As for the "port," it seems that the linux headers for stdarg and

: Also, the copy of the source code I found was simply missing a line

Are you using the patches to Net-Fax 3.2.1 ?  I am using NetFax on our local
Linux machine with success ! I have compiled the Clients to RS-6000 and
SUN-Sparc Systems. You must have a look at the Class 2 specifikation of
your Modem ! Not all Modems support the Class 2 Commands that NetFax uses.

Here ar the patches for Linux :

** Introduction:

   This is my port of netfax-3.2.1 to linux. Please see the License
   agreement in the file 'LICENSE'. It applies to the original source
   code and to my changes. 

   The port to linux was simple. once fd_set has been fixed in linux,
   this port is reduced to correcting few bugs and adjusting few
   header files. this port has been testing under linux 0.99pl2.
   Please not that I don't have another fax at my disposal for testing
   fax receive. I would appreciate it if you'll let me know how it
   goes if you can try it. I tried it once and got timeout errors. If
   you get the same errors tweeke the values in
   fax-3.2.1/lib/libfax/c2proto.h

   The rest of this file is instructions on how to install netfax on
   your system. Please also refer to the original documentations in
   the files "README" and "INSTALL". 

   All comments, bug reports, faxes :-) are welcome. 

 - Ziad Najem
   najem@cs.uiuc.edu


-------------------------------------------------------------------------

** Prerequisites:
  
   The following must be installed on your system for netfax to work. 

   *) TCP/IP must be operational. You only need the loopback part of
      it.

   *) the RPC library and header files. This should be part of the NFS
      package. last seen on
      tsx11:/pub/linux/BETA/NFS/sunrpc-src-4.0.tar.Z 

   *) Ghostscript. 'dfaxhigh' and/or 'dfaxlow' devices must be
      compiled in. if you're not sure if they are or not, at your
      shell prompt, type:
       > echo 'devicenames ==' | gs -DNODISPLAY -q -
      the devices should be in the list printed. 

   *) If you plan to fax regular text files, you need a filter to
      translate text into postscript. Netfax assumes enscript is
      available but that can be trivially changed. I have nenscript
      which is a publicly available clone of enscript. It compiles out
      of the box. If you want just to fax postscript files (say using
      dvips) then you don't need anything for this step.

   *) Finally, the original NetFAX source files. Consult archie about
      fax-3.2.1.tar.Z if you don't have it.


** Installation. 
   1) tar xzf fax-3.2.1.tar.Z
   2) patch < fax-3.2.1.linux.diffs
   3) cd fax-3.2.1
   4) customize as specified in the next section.
   5) make. handful of warnings should be seen.
   6) You should be able to try it out before installing the files in
      their perminant places. The only exception is that
      cmd/faxenq/faxenq must be copied into its place as specified in
      include/conf.h using FAX_ENQ_PROG.
   7) start the fax spooler: "cmd/faxspooler/faxspooler". You may want
      to set the log level -l from 1..7
   8) First, see if you can talk to the spooler. do a "cmd/faxq/faxq",
      you shouldn't get "can't connect to fax daemon" 
   9) If every thing is working so far. try faxing a postscript file
      using: "cmd/faxps/faxps -p <phone> <postscript-filename>"
  10) Let me know how it goes. 

** Customization. 

   Most configuration is done in the file include/conf.h here is a
   description of these that you need to set before you can compile or
   run NetFAX.

   #define FAX_DEVICE		"/dev/fax"
     set this to the serial port of your modem or make a symbolic link
     from /dev/fax to /dev/ttys<number>

   #define FAX_SERVICE		"fax"
     Make sure to add the following line 
     fax   <XYZ>/tcp 
     to the tcp/ip services file (either /etc/sevices or
     /usr/etc/inet/services). <XYZ> is some unique integer which is
     not used in the services file.

   #define FAX_HOST		"zodiac.slip.uiuc.edu"
     Your machine's host name.

   #define OUTGOING_QUEUE 	"/usr/spool/fax/outgoing"
   #define INCOMING_QUEUE	"/usr/spool/fax/incoming"
     make sure that these directories (or what ever you set the above
     two to) do exist. 

   #define INCOMING_EMAIL_ADDR "najem@zodiac.slip.uiuc.edu"
     if you have Mail working set this up. If you don't just create a
     dummy script in /usr/ucb/Mail which does nothing. 

   #define FAX_ENQ_PROG		"/usr/local/lib/fax/faxenq"
      Once compiled, copy cmd/faxenq/faxenq to whereever you set the
      above before trying to fax.

   #define FAX_PS_PROG		"/usr/local/bin/faxps"
      Unless you'll be using cmd/fax/faxps, you don't need to worry
      about the above when testing.

   #define PS_PROG  "/usr/local/bin/gs -dNOPAUSE -q -sDEVICE=dfaxhigh "
      Just make sure that full path to ghostscript is specified above.
      Don't change any of the options except the DEVICE in case you
      need to send a low resolution faxes. 

   #define PS_TO_COVER_PROG "/usr/local/lib/fax/coverpage.ps"
      Set this if you'll be using the -c option when sending faxes. 


 Hope I haven't missing anything. 
-------------------------------------------------------------------------------

Hope that will help you !
