I'm using the software in combination with a short PL2303 based USB to Serial cable, between a Windows 11 x64 laptop and a Book8088. The driver for Sewell's own cable does not seem to install, but with this table (manually set to COM1 in device manager) it works brilliantly - it even managed to send the DOS stub over the cable. You may need to set a lower speed for your transfer - with the Book8089 I find 38,400 baud to be reliable.
