AWR1843BOOST: use self-made serial program to control the device

Hello,

I am working with AWR1843.

If I make a serial program, send write say "flushCfg" command to AWR1843, then what is the desired response from AWR1843 through the serial port? What the AWR1843  response if the sent command is incorrect?

Is there any doc that introduce the response of the configuration command? I can only find the introduction on those commands. But there seems no introduction on the reponse for each command.

Best Regards,

Yinsheng Liu
