Re: [hylafax-users] faxgetty hangs

[Lee Howard <faxguy@xxxxxxxxxxxxxxxx>]

Lucie,

Please set:

TracingMask: 0x11
SessionTracing: 0xFFF

in your modem config file, restart faxgetty, and then send the log that 
gets stuck.

Your strace really looks like it's talking about a driver read block, 
but the session log with that verbosity should give us some clear 
indication.

Thanks.

Lee.
