Serial Program Mode
For Serial Program Mode, all commands must be framed by an STX (02 Hex)
and ETX (03 Hex).
To recall defaults:
1. Transmit <STX>999999<ETX> through the Serial Port. This will put the
scanner in serial program mode. Scanning will be suspended and the
scanner will respond with an ACK (06 Hex).
2. Transmit <STX>999998<ETX> through the Serial Port. This is the Recall
Defaults bar code in the MetroSelect guide. The scanner will respond with
an ACK (06 Hex).
3. Transmit <STX>999999<ETX> through the Serial Port. This will cause the
scanner to exit program mode and save the new settings. The scanner will
beep 3 times and send an ACK (06 Hex).
If at anytime, the scanner cannot recognize a command, it will respond with a
NAK (15 Hex).
