Set the stop bits to the same setting your terminal is using, or you want to use
with your serial port.

Half Duplex

This applies to use of the "F45-1 Serial Y Cable" only. "Full Duplex" means
that the R/F Reader will transmit data only through the HOST connector. With
"Half Duplex", data is transmitted through the HOST and TERM connectors.
Full Duplex should be used in almost all cases, but Half Duplex. 0 is useful for
testing pin-out reversal.
Protocol
This parameter only applies to a serial 2-way Base Station.
None 0
Host Controlled Acknowledge
1
"None" means that a serial 2-way Base Station will immediately transmit an
acknowledgement to the 2-way RF Scanner from which it has just received
transmitted data, (without waiting for a response from the host computer program.)
If you want the host computer program to analyze the data and to send back
different beep patterns to the laser scanner, enable Host Controlled
Acknowledge. With this parameter enabled, when the serial models of the 2-way
base station receives data from an R/F Scanner, the data is passed to the
computer and no acknowledgement is sent to the scanner until the host computer
replies to the base station with one of three possible ASCII codes: ACK (ASCII
06), BEL (ASCII 07), DC2 (ASCII 18). Upon receipt of these codes from the
host computer, the base sends a signal back to the transmitting laser scanner that
causes it to emit beeps as follows:
ACK - one short beep in laser
BEL - two longer low pitched beeps
DC2 - three longer low pitched beeps
This allows the host computer program to give limited feedback to the
scanner operator.
