Command Forms
Commands and queries have two different forms, long and
short. The command syntax is written with the short form of
the command in capitals and the remainder (long form) in
lower case.
The commands can be written in capitals or lower-case, just
so long as the short or long forms are complete. An
incomplete command will not be recognized.
Below are examples of correctly written commands.
Long form
SYSTem:BUZZer:KEYSound
SYSTEM:BUZZER:KEYSOUND
system:buzzer:keysound
