Hi Wendy, I see from another user list that you have used the dectalk express with a usb serial converter (the prolific usb to serial converter). I am using the same converter and have the following problem: When I press tab or arrow around quickly, jaws says "ra 250" or dv ap 100. Also speech seems slow and not very responsive. Have you had these problems? Would it help to use a usb 2.0 converter (the prolific one is usb 1.1)? I would have thought that a serial device such as dectalk express would not need more than usb 1.1. Ryan
