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.
