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 999999 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 999998 through the Serial Port. This is the Recall
Defaults bar code in the User guide. The scanner will respond with an
ACK (06 Hex).
3. Transmit 999999 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).
