7-3-1. Command Responses (Commands 1-6)
Echo and Prompt
Responses will be sent as shown below when receiving commands:
A command is received.
↓
Echo
@[sp]X:<Lvls>/<Dest>,<Src>[CR]
↓
Prompt
[CR][LF]>
* MFR units respond with an Echo Reply with the same data that they received. Therefore, echo reply
messages end with [CR][LF] or [CR] only. If echo messages with [CR][LF] are received, only [LF]
composes the second line.
* MFR units read a command, ended with a newline, and return a prompt to notify that they are ready to
receive a new command.
*
A carriage return and line feed are not added at the end of “Echo Reply” and “Prompt”
“C” responses
A “C” response is sent as shown below when a control command is received:
[CR][LF]C:<Lvls>/<Dest>,<Src>[
…
[S<
Salvo number
>][L<
Link number
>]]:I<ID>[CR][LF]
* C responses are sent to all the terminals in the system.
