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.

This parameter specifies how long the scanner waits for an ACK, NAK, or CTS before determining that a transmission error has 
occurred. This only applies when in one of the ACK/NAK Software Handshaking modes, or RTS/CTS Hardware Handshaking option.
