Erratic fax recv behaviour

[nicolc@elsie.econ.uregina.ca (Chris Nicol)]

Hi. I am running hylafaxv4pl1 on a Linux machine with kernel 2.0.27.
I am using a USR Sportster 33.6 fax modem, running in Class 1, since I
have never been able to get it to behave properly in 2.0. 

The modem is set to send and receive fax, but sometimes it works,
sometines it doesn't. Today, I had a lot of trouble receiving a fax.
Got it after about the sixth try. Here is the log file from one of the
failed sessions. Any ideas?? Thanks in advance for any help.
