Response The MODE SET response is the expected answer to the MODE SET request.
It indicates whether the operation for each station was successful.
The value in the status field for each station is 0 if the request was successful. If an
error occurred, some other value appears in the status field. The general status field
contains the code for the most recent error encountered.
If the request completed in an error for any given station, the station is in now in is
probably in DEAD mode with the ERRORSTOP condition.
For a list of the status codes and their definitions, see “Status Code Definitions” at the
end of this section.

Status := 0 if there were no errors, otherwise a code
for the most recent error
Request ID := The same as in the request
Text Out := 0
Text In := Number of stations x 2
Text := For each station named in the request:
Station ID :Byte
Status :Byte
0 = Completion without error, or an
error code if the request was
