Hi Laurent: The appropriate settings are almost the default, 9600 n, 8, 1 with hardware handshake. The unit gets best results with the chord-s speechbox mode. If that doesn't work automagically you can specify speakup_ser=1 for com2 on the boot line after typing linux. So for example at the boot prompt you would type: linux speakup_ser=1 You use 0 for com1 and so forth. We have rewritten parts of that driver in the cvs code but I don't suggest you use that until you have a good understanding of linux first. good luck Kirk -- Kirk Reiser The Computer Braille Facility e-mail: kirk at braille.uwo.ca University of Western Ontario phone: (519) 661-3061
