for the same interface.
SOLUTION
Try operating the scanner in Alt
mode.
Increase the intercharacter delay
setting. Adjust whether the
F0 break is transmitted (KBW
Interface ONLY). It may be
necessary to try this in both
settings.
Enable the caps lock detect
setting of the scanner to detect if
the PC is operating in Caps Lock.
Check to make sure that the
baud rate and parity of the
scanner and the communication
port match and the program is
looking for "RS232" data.
Check that the scanner and the
host are configured for the same
interface.
