[Asterisk-Users] A software FAX modem

[Steve Underwood]

Hi,

Interesting. I am using RH9 for testing. The only piece of libtiff that 
was missing for me was tiffiop.h. That is why I put a copy on the FTP 
site. Do you have the libtiff-devel package installed? None of the 
libraries can be used to build anything on RH without the xxxx-devel 
package installed.

It seems you are not the only one getting this coredump. I assume you 
are using exactly the same libtiff as me, since you are using RH9. 
Strange. Still, it seems people are getting some communication at the 
V.21 and V.29 modem level now. That is certainly progress :-)

I will try to provoke the software some more, and see if I can reproduce 
this problem. I have sent a couple of rolls of FAX successfully from my 
soft-fax to a real FAX machine (plus some that didn't go so well, of 
course), and quite a few files the other way. This thing really is 
basically capable of working in its current state.

Regards,
Steve
