End of Packet
Controller-to-Target – This is the 'Carriage Return' ([CR]) character (ASCII code 13).
Target-to-Controller – This is the two-character sequence 'Carriage Return', 'Line Feed' ([cr][lf]) (ASCII codes 13 and 10).
Both indicate the valid termination of a packet.
Serial-Based Remote Product Management
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, MUT* (with message arguments).
If the Controller sends an instruction code which the Target cannot currently perform because of
hardware resource issues, then the Target will acknowledge the message by echoing the invalid
instruction, followed by the # character. This response can only occur if the operator sends two or more
'hardware configuration' type commands without allowing adequate time between commands for the
hardware to be configured. For example, if the operator issued commands to change both the
frequency and the attenuation with less than 100 milliseconds between commands, and if this response
is returned, then the command has not been accepted and the operator must resend the command.
