I don't see why an USB/232 adapter that works with all systems I have tested (drives, PLCs, development systems, measurement interfaces) shouldn't work in his case - which we do not know much about.

RE: laptop usb port
A-B's problem stems from the 1747-PIC being quite an old product. It draws power from the port, and is quite power-hungry by the modern standards. The power requirement is met by the original PC/AT serial port spec from years ago, but more modern computers are able to supply less power from their serial ports. Laptops are probably the worst in this respect, but my PIC doesn't work reliably with newer desktops either. A-B's solution, as you might guess, is 'buy different hardware'.
I wonder if it is practical to incorporate a small external power source to run the PIC?
