# z8530\_status(9)

Handle a PIO status exception

## 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.
