the slave will acknowledge the message by echoing the invalid instruction,

The # code (slave to master) is only used as follows:
• If the master sends an instruction code which the slave cannot currently
perform because of hardware resource issues, the slave will acknowledge
the message by echoing the invalid instruction, followed by the #
character.
• This response can only occur if the operator sends two or more ‘hardware
configuration’ type commands without allowing adequate time between
commands for the hardware to be configured.
Example; the operator issued commands to change both the Up
Converter frequency and the down converter frequency with less
than 100 milliseconds between commands
• If this response is returned the command has not been excepted an the
operator must resend the command.
