Old tele man, I just bought one off of Ebay from Auterra, but I cannot get it to work properly with my Handspring Visor Prism or my Palm T3. I have partial functionality for now. Their tech support did tell me I specifically that the A-300 must have a direct serial connection, and they had to manufacture their own serial cables for most of the Palm series. I sent them pix of my screenshots with the errors, so I hope they can figure it out. Soon.
