The log file indicates pretty much the same thing that you're telling us 
here: that the modem firmware has locked up.  To verify that HylaFAX has 
concluded this correctly, you should (when this happens) disable 
faxgetty and then run minicom on the modem and try to "wake" it up.  
(Maybe try "ATZ" or "AT&F" or just plain "AT".)

If you can't wake it up, then the modem apparently will need to be 
power-cycled to wake it up.  This will require a reboot if it is an 
internal modem.

I don't think that the USRs and this had a common problem... unless you 
have some other hardware sharing IRQ 3.  Normally, however, I've not 
known USRs to lock up like this very often.  They do crash, yes, but 
they reset themselves when they do.  It may be some kind of serial 
misconfiguration of some kind, too.  But most probably it's a firmware 
issue.  After all, the modem is probably 12 years old now.
