Command String

A command string consists of multiple commands on one line. The maximum length of a
command string is 32 characters. All command strings are terminated by the Carriage
Return <CR> code (0DH hex).
Example :
NOTE: The Real Time Clock Set (WW) , Print Character (PR), Blackboard/Stack Data
Upload (BU), Blackboard/Stack Data Download (BD), Weekly Timer Data Upload
(WU), Weekly Timer Data Download (WD), Text File Data Upload (UU) commands
should be assigned individually.
Once the <CR> termination command is added to the string, the command string is
evaluated and executed from left to right in sequential order.
If an error occurs during the execution of a command string, the remainder of the string
following that command is not executed.
If a new command string is input before the execution of the current string is complete,
the current string is aborted and the remaining commands are cleared.
To cancel a currently executing string, send the termination command <CR> alone.
If a new command without Text File Data Upload (UU) is input while the execution of
the current command stack, the remaining of the current command stack are cleared.
