Actually this is being worked on. I have sent email to the manufacturer (Access Solutions) last week about getting the specs. I'll let you know what happens there. I own a triple talk USB myself, so I am looking at writing the driver for it to start with, then probably the dectalk USB. I'll probably start with kernel level device drivers that create a device in /devso they can be accessed from user space then figure out how to integrate them into speakup. Thanks, William
