Host Serial Response Time-Out - Symbol LS 4008i Product Reference Manual

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 Host Serial Response Time-out 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.

Host Serial Response Time-out

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.
