Examples of External Control Strings
Example 1 AUXB12^M
This will transmit AUXB12 out of the serial port, and will
terminate with a ^M (carriage return).
Example 2 ^@C0^@00^@02^@00^@15^,^,^,2!^C
This will transmit the hex characters C0 00 02 00 15, pause
for 300 milliseconds, and then send the ASCII characters
2! followed by a control-C (break).
NOTES:
• Most devices expect some kind of ‘termination
character’ at the end of a control string. Control-C ^C
(break) or control-M ^M (carriage return) are used
most frequently; however, this is totally dependant on
the hardware you are controlling. There is no
‘standard’ for termination characters.
• Any spaces entered within the data string will be
transmitted just like any other character. You should,
therefore, avoid entering or leaving spaces in a data
string, unless they are specifically required by the
receiving device.
