I use a Belkin RS232 to USB converter as you can still get drivers for
these.

If Windows 10 sees a USB COM port it will naturally use its own drivers.
Prior to Windows 10 COM ports were a nightmare, hence the FTDI debacle.

It might be worth plugging in your old converters into a Windows 10
machine to see if they are recognised before binning them.

The MC145406 changes from TTL levels to RS232 levels. You can get very
cheap TTL level RS232 USB converters though they don't always come with
all the signals I believe you might need.

Nice project.
