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 waits up to 2 seconds for an
XON character before transmission. 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.
