flexfax: EOL problem

[Ermelindo Mauriello <inmaer@inteltec.it>]

I've installed HylaFax on Linux - RedHat 6.1 (precompiled package
4.1beta1-1rh6). Sending FAX is OK. On receiving I got 
"FaxGetty[2375]: RECV FAX (00000005): session with  
terminated abnormally: Missing EOL after 5 seconds (section 3.2/T.4)"

I'm using a MODEM GVC ROCKWELL 288DPI/KB3426-04 and faxgetty to recevice faxes.

What does it means and how I can resolve the problem ?
Thanks
