Character Definition
!
(ASCII code 33)
If the Controller sends an instruction code that the Target does not recognize, the Target responds by echoing the invalid
instruction, followed by !
Example: CMD!
*
(ASCII code 42)
If the Controller sends the command to set a parameter to a particular value, and the value sent is valid BUT the router will
not permit that particular parameter to be changed at present, the Target acknowledges the message and responds with,
for example, CMD* (with message arguments).
#
(ASCII code 35)
If the Controller sends a correctly formatted command, BUT the unit is not in Remote Mode, it does not allow
reconfiguration and responds, for example, with CMD#.
