Length of APDU
(System-specific parameter, specify the maximum length of the APDU per
system)
The Maximum length of the APDU is 246 (default). The maximum length may be
reduced by the system.

Process information in monitor direction
(Station-specific parameter; mark each Type ID "X" if it is only used in the
standard direction, "R" if only used in the reverse direction, and "B" if used in
both directions)
