><P
> The PPP system contains two threads, One is used for receiving
data from the link and processing control packets. The other is
used to transmit data asynchronously to the link when it cannot be
completed synchronously. The receive thread runs at the priority
given here, and the transmit thread runs at the next lower
priority. The exact priority needed here depends on the
importance of the PPP subsystem relative to the rest of the
system. The default is to put it in the middle of the priority
range to provide reasonable response without impacting genuine
high priority threads.

><P
> The runtime <CODE

high level debug messages. Too many of these can interfere with
the PPP device and may result in missed messages. This is because
these messages are emitted via the diag_printf() mechanism, which
disables interrupts while it prints. By default, therefore, we
only report errors and warnings, and not all events. Setting this
option to zero will enable the logging of all events.
