z8530_status - Handle a PIO status exception
void z8530_status (struct z8530_channel * chan);
chan Z8530 channel to process
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.
