Have to agree that usb is rubbish. Was at an arizona microchip training course a few years ago when they were first bringing out pics with onboard usb. Took the guys a day to get it to send simple ascii characters. Best bet is to get a pci rs232 card if you have a desktop or pcmcia card for a laptop. I have both and work fine with my own projects and rtd explorer. Trouble with most usb to rs232 adaptors is that they are implemented in software.
