Basic format for control data
The transmission of control data from the computer starts
with a STX signal, followed by the command, the
parameters, and then an ETX signal in that order. If there
are no parameters, then the parameter signal does not
need to be sent.

Note:
(1) If multiple commands are transmitted, be sure to wait
for the response for the first command to come from
this unit before sending the next command.
(2) If an incorrect command is sent by mistake, this unit
will send an "ER401" command back to the computer.
