Connecting RS232 Devices
If you want to connect two DTE devices (data terminal equipment,
such as a PC), you have to cross-connect the data lines and the
handshake lines of the two RS232 devices.
To do this, connect the pins of the devices as shown below. This
method is known as 'null modem cabling'.
