8 - 14 Symbol DS6707 Digital Imager Scanner Product Reference Guide

XON/XOFF: An XOFF character turns the digital imager scanner transmission off until the digital imager 
scanner receives an XON character. There are two situations for XON/XOFF:
• The scanner receives an XOFF before it has data to send. When the digital imager scanner has data to 

send, it waits up to Host Serial Response Time-out for an XON character before transmission. If it does 
not receive the XON within this time, the digital imager scanner issues an error indication and discards the 
data.

• The scanner receives an XOFF during a transmission. Data transmission then stops after sending the 

current byte. When the digital imager scanner receives an XON character, it sends the rest of the data 
message. The digital imager scanner waits indefinitely for the XON.
