This function is called from the Workplace Shell and allows the port driver to remove its data from the INI file.

The port driver must remove the printer port from the system INI file by removing ApplicationName "PM_SPOOLER_PORT" and KeyName "pszPortName". The port driver should also remove its own data for this port from the system INI file by removing ApplicationName "PM_<pszPortName>", where "pszPortName" is the designation of the port in question.
