Will have to look into this. I haven't tried using the blazer over parallel for a few years, so tried it again a couple of days ago with a windows screen reader. There is no hand shaking of any sort over parallel as far as I can tell. Once the parallel port is selected as the output port in the screen reader I'm working with, other serial options, including hand shaking are disabled. As far as using the blazer over parallel, it seems to be just dump and wait. Once the screen reader starts sending speech to the blazer, there is no way to interrupt until the speech is done. This does include indexing of course as well. Looking at the parallel communication between the blazer and the screen reader, I see no attempt by the screen reader to read the parallel port in any way. All it does is just write data one way. I will check the blazer manual to see if it has anything to say about using the parallel port with a screen reader, other than stating this is possible. Using the blazer over parallel is never my first choice. However, it's better than nothing if a serial port or a usb to serial converter aren't available, and it's either parallel or nothing.
