6. To enter serial program mode, send the following command
[stx]999999[etx].
7. To exit serial program mode, send the following command [stx]999999[etx],
the scanner will respond with an [ack] and a long beep.
8. This mode uses the current Baud Rate, Parity, Stop Bits and Data Bits
settings that are configured in the scanner. The default settings of the
scanner are 9600, Space, 2, 7 respectively. If a command is sent to the
scanner to change any of these settings, the change will NOT take effect
until after serial program mode is exited.
EXAMPLE #2: The following example will set the scanner to the factory
default settings, Disable Scanning of Code 128 bar codes, change the
beeper tone, and add a “G” as a programmable prefix.

The scanner will emit a long beep!
The commands sent to the scanner do not include the small superscripted
‘3’ that you see in front of each bar code string in the MetroSelect
® manual.
THE ‘3’ SHOULD NOT BE SENT, IT IS A CODE TYPE DESIGNATION
ONLY!
As you will note for commands requiring additional bar codes to be
scanned (such as prefixes, suffixes, timeouts, etc.), simply send the code
bytes in the same order that you would normally scan the bar codes.
