to support some form of
host handshaking but is
not receiving the signal
If the scanner is setup to support
ACK/NAK, RTS/CTS, XON/XOFF
or D/E, verify that the host cable and
host are supporting the handshaking
properly

the data
transmitted to the
host is incorrect

does not match the host
system requirements
Verify that the scanner’s data format
matches that required by the host.
Most sure that the scanner is
connected to the proper host port
