Serial Pin-Outs	by LthrOttr	2006-07-12 17:27:02
For a standard RS-232 Connection: 9-pin: 1 - Carrier Detect 2 Receive Data 3 Transmitted Data 4 Data Terminal Ready 5 Signal Ground 6 Data Set Ready 7 Request to Send 8 Clear to Send 9 Ring Indicator I'm not sure what you are referencing by TIOCM_CAR. Pins 7 and 8 are used for hardware flow control, normally, on a port. I don't explicitly remember all the pin groundings for a null modem, though. It's been a while. I think DTR is shorted to ground, and 2 and 3 and 7 and 8 are crossed.
