.SH "DESCRIPTION"
.PP
This function informs the synchronous protocol code that
the underlying link died (for example a carrier drop on X.21)
.PP
We increment the magic numbers to ensure that if the other end
failed to notice we will correctly start a new session. It happens
do to the nature of telco circuits is that you can lose carrier on
one endonly.
.PP
Having done this we go back to negotiating. This function may
be called from an interrupt context.
