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. We communicate that back to  the  protocol
       layer for synchronous PPP to renegotiate.
