[Coco] Bit Banger Port Signals

[Gary Becker]

I had a question about how the Bit Banger Serial port is being used. The three signals are labeled in the service manual as RS232C OUT, RS232C IN, and CD. How are people using the CD pin? If it was hooked up to a modem, the CD pin would indicate a connection was made by the modem. But since modems are not used much any more, does this pin really make sense? I thought using it for a CTS would make more sense. Is anyone using it for this function? Is anyone using it at all?
