Hi all, I'm using txfax and rxfax to send and receive faxes. I find that txfax performs very well when sending to an old fax machine. However, when trying to send to a Mac (OS X) that accepts faxes, I get a "Trainability test failed" message on the * console (full console log below). I'm OK with being unable to fax to Mac, as I'm just using it to test. For future reference, I'd like to know what causes this problem, and what steps (if any) I can take to correct it. Thanks Ryan exten => out_f...

Hi all, After a long time having no time, I have finally done some fresh work on my software fax machine. I have replaced the original carrier tracking with something more robust. I have also added 4800, and 2400 bits per second modes, and cleaned up a few bugs in areas like superfine mode operation. I apologise for this update taking so long. At ftp://ftp.opencall.org/pub/spandsp you will
