SerialCommunicationProtocol
This protocol is based on a master sending commands and a node
answering. The whole communication is conducted in plain ASCII, as
strings, and numbers are represented in decimal format. All
commands are terminated with a CR/LF combination. All responses
(answers) are terminated with the # character.
GeneralFormatofaCommand
The commands have the following format:
ID Command Param1 Param2 ... ParamN
•
ID is the destination device. If you include an ID as part of a
command, the node checks whether ID=ownID. If it does, the
node executes the command on itself. If the ID is not the node’s
ID, the node executes the command on a remote device, if such
an ID exists. If the ID is missing, this implies that the command
is addressed locally.
Note: Not all the commands can be relayed remotely.
