The stats –p command displays statistics for all parallel ports:

The superuser stats –c command clears all serial line statistics to zero.
The stats –m command displays statistics for active control lines, but
displays the modem controls for inactive control lines rather than
displaying idle.

Monitoring Serial Line Activity

The Annex provides two superuser CLI commands that display
information about the state of the Annex's serial ports: control and tap
(see control on page A-141 and tap on page A-205 for more details).
The superuser CLI control command is a diagnostic tool that, for a
specified port, allows you to set DTR and RTS or output a short test
message. The superuser CLI tap command accesses (wire taps) a serial
port from a terminal.
The tap command will not work with PPP.
