windows program to read papertape from reader through serial port

Python scripts for working with papertape, including Pass it the
COM port and baud rate as arguments. I have not run it on windows but
should work, I have digitized a significant number of tapes with this

As far as flow control, you can look in the python code. It uses pyserial,
which supports enabling HW flow control:

More likely your issue is DTR or similar. You may need an RS232 light box
for debugging. Here is a sample from Amazon.

Good luck, if you keep facing issues feel free to contact me off list for
assistance. I can almost guarantee your comms issue is either your USB
adapter (prolific chipset is a good one) or your cable/adapter, not SW.
Your SW problem is easioy solved by using those python scripts I linked
which can work with raw binary over RS232. Teraterm and similar deal with
characters, not bimlnary data.

Worse comes to worse I have an excellent paper tape workflow and am willing
to digitize a few tapes if they are historically significant.
