A hardware overrun occurs when the data in the serial port buffer is not
moved in time to another location before new data "overruns" it.  Hence, a
"hardware overrun." The Amiga's built-in serial port is very poorly
buffered and any system activity can "steal" the window of opportuinity
when the data from the serial port would nomally be shifted out.  The GVP
SCSI host adapter makes this problem especially bad since large transfers
from a fast device can saturate the bus for long periods of time.

(See the I/O Extender or the SCSI section for more details.)
