I think it may be best to break this problem down. While we can establish that the synth itself works with the use of another machine it will not further assist with the target machine. Next thing I noticed is that you can no longer get your synth to work on the target machine with a DOS boot disk and screen reader. Since this used to work, I think we can safely say it is probably not a linux problem. Can you get sighted assistance? I wonder if your serial ports are configured correctly. Did the target machine have an working OS with speech in its current configuration before starting with Linux? I suspect you have a port problem. Since you seem to be familiar with DOS I would stick to the DOS boot disk and get it to work properly with the desired synth before going forward. If the hardware isn't configured properly all bets are off. -- Kirk Wood Cpt.Kirk at 1tree.net ------------------ Seek simplicity -- and distrust it. Alfred North Whitehead
