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