TEST/FAX_ROUTING may be used to test entries in the FAX_ROUTING
    mapping tables used by the DATA_TO_BITMAP channel of PMDF-FAX.
    These entries are used to alter, on a per received FAX basis, the
    processing options used by that channel.

    The specified routing will be looked up in the FAX_ROUTING
    mapping table and, if found, the mapping result-a list of
    processing options for the DATA_TO_BITMAP channel-will be parsed.

    If a routing is specified on the command line, TEST/FAX_ROUTING
    acts upon the specified routing and then exits. If no routing is
    specified on the command line, then TEST/FAX_ROUTING will prompt
    for routings until a CTRL/Z is entered.
