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

[RS232] requires you to select a transmit/receieve rate called a baud rate. [PC]s commonly support up to 115200 baud. Almost everything defaults to 9600 (although not always). |
