Well, Nick, I am running a Dec-Talk U S B with speakup in serial mode. When I flip the switch, it says rs232. Yes, I also notice if I am arrowing around the screen in review, the pitch and rate both get knocked down. At that point especially moving the pitch up or down will fixit again. I am still having an odd problem while reading a pine index with speakup, where either speakup or the dec-talk are swopping around the date and message number. We practicly got YASR running, so I will try it-and-see if the same thing happens. As far as the dec-talk unit itself, they claim I can ajust the treble? Might you know which command-and where will I type it? Thanks in advance Hart
