COMMAND STATUS RESPONSE (CSR) CODES—RS-232, AE BUS

When the host sends an executable command or a command requesting a change in a
parameter setting, the Apex generator returns a command status response (CSR) code
indicating whether the command was accepted or rejected and, if rejected, why. Table
4-5 defines how these CSR codes should be interpreted.
