A usb to serial converter won't do any good for talking to a serial synth. The reason is that the i/o ports for the uarts are not the same and we speak to the ports at a very low level. I am trying to find time to include usb and pcmcia support. Kirk -- Kirk Reiser The Computer Braille Facility e-mail: kirk at braille.uwo.ca University of Western Ontario phone: (519) 661-3061
