[NOEL POULIN]

Hello
I am wiring my own KXSER Rs232 cable ...DB9F TO 3.5 MM JACK
Here is what I have for connections.
DB9F                                       3.5MM JACK
pin 3........................................Tip
pin 2........................................Ring
pin 5........................................Sleeve.
I saw somewhere that pins 4 (DTR) AND PIN 8 CTS) on the DB9F must be 
connected  together....
I AM NOT SURE...
Anyone can tell me if those pins 4 and 8 must  be together....(CONNECTED)

Thanks
Noel
