Example: To instruct the controller to send the utility parameters the computer
would send:
Chr$(255)+Chr$(254)+Chr$(1)+Chr$(2)+Chr$(0)+Chr$(253)
4. Receive utility parameters (Code #3)
Instructs the controller to enter all the incoming utility parameters into memory.
5. Send controller time (Code #4)
Instructs the controller to send the current time and date to the host computer.
The time and date are sent as strings. A description of the time and date
parameter list is as follows:
