Fifo Overflow

[R. J. Auletta]

On a VAX3600 running Ultrix 3.1 with a Hayes Government Modem
the following errors are reported on the console and by uerf 
occasionally after a dialin session is terminated.
The rd and sd lights on the modem are full on.

I looking for a better understanding of the error to help track
down the cause (modem, configuration, hardware fault) as
this hangs the machine until the modem is turned off.
