Thanks so much for your reply. F11 in NUM_MMI? When U say parameter page are you referring to the edit_pp.ini file? This gives the option to select com1 or fipo. Which I have done and still no joy. And I have null modern cable too. Any chance I can chat with U via an email? I would like to send some pics of what I am doing. I was told be another NUM guy I need to edit parameter 112. Which I have no idea how access this via my old windows 3.1 computer.
