7. Receiver Inter-character Timeout:
When serial interfaces with asyn-
chronous character framing are
used, this parameter indicates if the
receiver makes a check for gaps
between characters (i.e. extension of
the stop bit time of one character
prior to the start bit of the following
character within a message). If the
receiver performs this check and the
timeout is exceeded then the
receiver discards the current data
link frame. A receiver that does not
discard data link frames on the basis
of inter-character gaps is considered
to not perform this check.
Where no asynchronous serial inter-
face is fitted, this parameter is not
applicable. In this case none of the
options shall be selected.
8. Inter-character gaps in
transmission:
When serial interfaces with asyn-
chronous character framing are
used, this parameter indicates
whether extra delay is ever intro-
duced between characters in the
message, and if so, the maximum
width of the gap.
Where no asynchronous serial inter-
face is fitted, this parameter is not
applicable. In this case none of the
options shall be selected.
