This clears out all currently closed PAR buffers, thus preventing any
further output. Any channels which are open to the PAR port will be left
unaffected.

**NOTE**

Although the SMSQ/E implementation allows a port to be specified, there
are currently no implementations of the QL which have more than one
parallel port, therefore trying to pass a port\_number at present
results in a bad parameter error.

**CROSS-REFERENCE**

:ref:`ser-clear` and
:ref:`prt-clear` are similar.
