Some Problems Develop with the Modem

I have been working with the modem for the AERCO system and have run into some difficulty. I have tried to use the Specterm-64 program from Grey and Associates. I have also attempted to get the version of Modem? to work with the modem with no luck. I went to the FWKUG and received some Modem programs to try out, each one being a failure. I was getting desperate with all these failures and not knowing exactly what to do. I sent Chuck Dawson a letter to see if he could figure out what I was doing wrong and received an interesting answer.
