We've had a couple of different 2400 baud modems on our MicroVAX,
and with both the machine would crank out the same errors
("dhu0, line0: recv. fifo overflow").
One night the system console ran through about 100 pages of paper while
printing error messages before the paper jammed.

The modem lights rd and sd were on constantly when we got these errors, too.

We replaced the 2400 baud modem with a Telebit T2500, and we have not
seen the trouble since.
