Now that I have dsl and took out my internal modem, I have braillelite on com1 (for brltty) and doubletalk on com2. I want to make sure speakup uses the doubletalk on com2 rather than trying to use the braillelite. Is there something I need to do to make this work. I plan to sometimes use the brltty and speakup programs at the same time. thanks. Cheryl
