Z8530_STATUS(9)                         Internal Functions                        Z8530_STATUS(9)



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.
