Try shorting pins 5 to 6 or pins 5 to 8 on the 5420, The 5420 will work (as you have noted) , but not full function. >Another problem I have noticed is using the Hayes to call into >our computer.

The computer times out and disconnects the >call. Anyone else notice this problem? What speed is your terminal running? I have a USR2400 modem. If I have my terminal set to 2400baud and I connect to a 1200 baud modem, I get the "Connect 1200" message at 2400 baud but then the modem switches to 1200 baud and the terminal must be switched manualy to 1200 in order to converse with the computer.. tnx Gary W.
