Each instruction must not exceed 15 characters.
Every instruction must end with ";" or with a return character
to indicate that the instruction set is sent out. The ASCII code of
a new line character is 10, but it is indicated by "\n" in C
language. If there is no ending character in the instruction set,
the instrument may “lock up” and be restarted.
There should be sufficient time between two instruction so as
to allow enough time for the instrument to finish the current
operation.

capability.
Pressing "Trig" key once, the instrument enters into
triggered mode. The LCD will display "trig" on the bottom right
