I don't remember that one, but I had one for my Atari 8-bit computer. I connected with several computers at our local NBA arena back in the 80s by starting the dialing sequence at the arena's main number. They required passwords to go any farther than a simple "Enter Password" screen.
Was the ADAM one written in Basic?
Does anyone remember a program called the "War Games Smartdialer"? It used the Adamlink modem to find other modems to connect to by automatically dialing phone numbers. The name, of course, is based on a similar program that the protagonist in the movie "War Games" used.
