call 02 0a
response 04 0a 00 nn no fractions,
nn modules in the ring
04 0a 01 nn fraction before modul nn and
before the line in of the receiver
of
module C1300
04 0a 01 ff fraction cannot be localized
(fraction before receiver line
in)
in case the fraction cannot be localized, the probable location is between the last
module and the receiver line in of the C1300.
