RS232 is a standard for serial connections. In theory there are two ends to a RS232 connection a [DTE] and a [DCE].
-RS232 uses pin 7 for ground, and pin's
2 and 3 for transmit and recieve
. Other pins are used for hardware flow control, Ring indication etc.

RS232 requires you to select a transmit/receieve rate called a baud rate. "Standard" PC's support up to 115200 baud. Almost everything defaults to 9600 (although not always).
