Programming Via Escape Sequences
5–5
The following escape sequences cannot be concatenated with any other
escape sequences.
Esc – y <n> A Reader Address
Esc E Reset
Esc – y <n> I Code ID Character
Esc – y <n> N Header
Esc – y <n> O Trailer
Esc – y <n> Y No–Read Message Selection
To change your configuration to the following,
• Selected codes are to be UPC and Code 39 – [5f]
• Code 39 check characters are to be verified and transmitted – [9 g]
• XON/XOFF pacing is to be enabled – [1 x]
you could send any one of the following six escape sequences to your
decoder:
Esc – y 5 f 9 g 1 X Esc – y 9 g 1 x 5 F Esc – y 5 f 1 x 9 G
Esc – y 1 x 5 f 9 G Esc – y 9 g 5 f 1 X Esc – y 1 x 9 g 5 F
To save the new configuration in EEPROM you could send
Esc – y 5 Z as a
separate escape sequence, or append it to the end of any one of the above
escape sequences.
For example,
Esc – y 5 f 9 g 1 X would become Esc – y 5 f 9 g 1 x 5 Z.
Note that the capital X became lower case to accommodate the 5Z.
