I have had UUCP up and running on my machine for several years now, starting with ver 0.9a.
I just upgraded to 1.2.1, and am running into a interesting snag. 

I have a 66Mhz 486 System 32M RAM with an External Supra 28.8 modem interfaced to a
Hayes ESP serial port.

The system works fine most of the time, save for getting "ERROR: Timed out waiting for packet"
occasionally on large news downloads. But, every once in a while uucico locks up so tight, I need
to reboot the system. Here are the messages:

Now if I don't Power-down and Cold boot the system, uucico can't talk to the modem! I have to
initiate a Cold-boot. Then everything's fine.

This stuff never happened when I was running 1.2. Any Ideas!
