c) The * code (slave to master) is only used as follows:
i)
If the master sends an instruction to set a parameter to a particular value, then, if the value sent in the argument is valid, but the CSAT
will not permit that particular parameter to be changed at that time, the slave will acknowledge the message by replying with (for
example) with UAT* (with no message arguments).
d) The ! code (slave to master) is only used as follows:
i) If the master sends an instruction code which the slave does not recognize, the slave will acknowledge the message by echoing the
invalid instruction, followed by the ! character. Example: XYZ!
e) The # code (slave to master) is only used as follows:
i) 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.
ii) This response can only occur if the operator sends two or more hardware configuration type of commands without allowing adequate
time between commands for the hardware to be configured.
Example:
The operator issues commands to change both the up and down converters’ frequencies, with less than
100 milliseconds occurring between commands.
iii) If this response is returned the command has not been accepted and the operator must resend the command.
