Wasp's Serial-to-Keyboard program is a simple program that can be installed and
used to test the serial connection. It accepts serial input, then sends it to the PC as if
typed by a keyboard. It has a one-line "Last Scan" display field (screenshot below),
and can be used in conjunction with a text editor such as Notepad to show scanned
barcode data. It can be downloaded here:

Some programs will have trouble receiving data if the serial settings don't match in
Device Manager and the receiving program. Here's an example of matching
settings:
If you still encounter problems with getting an SPP mode scanner communicating to
Windows, there are several registry settings that can be cleared. Remove the paired
scanner, clear the registry entries, then try the pairing process again.
1. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\COM Name Arbiter\ComDB
