XON/XOFF
An XOFF character turns the scanner transmission off until
the scanner receives an XON character. There are two
situations for XON/XOFF:
• XOFF is received before the scanner has data to send.
When the scanner has data to send, it then waits for
an XON character before transmission. The scanner
waits up to 2 seconds to receive the XON. If the XON
is not received within this time, the scanner issues an
error indication and discards the data.
• XOFF is received during a transmission. Data
transmission then stops after sending the current
byte. When the scanner receives an XON character, it
sends the rest of the data message. The scanner waits
indefinitely for the XON.
