ON/XOFF
An XOFF character turns the scanner trans-
mission 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.
