Parameter # 9Fh

hardware handshaking. Hardware handshaking is always enabled and cannot be disabled
by the user.

When this option is selected, the decoder neither generates nor expects ACK/NAK
handshaking packets.
Disable ACK/NAK
(00h)
Enable ACK/NAK Handshaking
When this option is selected, after transmitting data, the scanner expects either an ACK or
NAK response from the host. The scanner also ACKs or NAKs messages from the host.
The scanner waits up to the programmable Host Serial Response Time-out to receive an
ACK or NAK. If the scanner does not get a response in this time, it resends its data up to
two times before discarding the data and declaring a transmit error.
*Enable ACK/NAK
