Code 39 Buffering
While there is data in the transmission buffer, deleting Code 39 buffering 
capability via the parameter menu is not allowed.
To allow disabling of Code 39 buffering, first force the buffer transmission (see 
) or clear the buffer.
Buffer Data
To buffer data, Code 39 buffering must be enabled, and a symbol must be read 
with a space immediately following the start pattern.
Unless symbol overflows the transmission buffer, unit gives hi/lo beep to 
indicate successful decode and buffering. See 
Unit adds the message, excluding the leading space to the transmission 
buffer.
No transmission will occur.
Clear Transmission  Buffer
To clear the transmission buffer, read a symbol which contains only a start 
character, a dash (minus), and a stop character.
Unit issues a short hi/lo/hi beep to signal that the transmission buffer has 
been erased, and no transmission has occurred.
Unit erases the transmission buffer.
No transmission will occur.
