Single Read Mode
In this mode, a single bar code symbol may be read only
after an
Enable Next Read command has been received by
the decoder. This allows the software in the host computer
to control when bar code data is entered into the system.
When single read mode is enabled, bar code symbols
will not be decoded until the
Enable Next Read escape
sequence is sent from the host to the decoder.
The Enable Next Read command can be found on page
