.SH "DESCRIPTION"
.PP
A status event occurred in PIO synchronous mode. There are several
reasons the chip will bother us here. A transmit underrun means we
failed to feed the chip fast enough and just broke a packet. A DCD
change is a line up or down. We communicate that back to the protocol
layer for synchronous PPP to renegotiate.
