I was out to a new customers this past week and was asked if we could directly connect their computer to the controller board, the unit is an Intellicon delta 88. Currently they are dialing into the board but have cut off their phone line to the unit by mistake as they switch phones services to the cable company :/

I can't get a signal from the serial port at all, the pins are not labelled and from little documentation it leads me to believe the port has to be enabled via software first.

Help any would be greatly appreciated.
