[Asterisk-Users] A software FAX modem

Hi,

I did say this was a first test release :-)  I can't be held responsible 
for libtiff being empty on your machine, but they other issues are my 
fault. I have put a new tarball up, which should need nothing more than 
libtiff for the library to work. All the other libraries you had issues 
with are only needed by the test programs. "./configure" will now only 
set things up to build the library. "./configure --enable-doc 
--enable-tests --enable-itutests" will set things up to be everything.

This newer tarball also has improvements in the software. The V.29 modem 
now works at all three speeds - 9600, 7200, and 4800bps. Previously I 
had only debugged the 9600bps mode. FAX doesn't actually use the 4800bps 
mode, but I thought I ought to fully implement the spec. (thats another 
way of saying it was easy to do after getting 9600 and 7200 working :-) 
). I also fixed something that could cause crashes if you tried to send 
a non-existant TIFF file.

I'm sorry if I disappointed the early adopters, but it *will* get better.

Regards,
Steve
