Commands
All commands and responses consist of printable ASCII characters. Commands are
typically three or four letter mnemonic codes followed by a parameter, if required. All
commands and responses are terminated with a <Carriage Return> (CR, 0x0D, \r) character. If a
CR terminated string is received, but a valid command is not found, a response of “Command
ERR” is sent.
The commands are shown in Table 9, “Interface Commands” as all uppercase for clarity;
the actual commands are not case sensitive. A space character is also shown between the
command and parameter for clarity. The space is not required.
Every command generates a response. The responses generally consist of the command
echoed back. If there is a returned value, it is separated from the echoed command by a “:”
character.
