We need to use some of the generic GPIO as serial ports, which can be acheived through 'bit-banging' the GPIO. FT232R USB UART The device has the following. I am not able to connect to it with windows IoT (C# program using .GetDeviceSelector('COM#'), where # = 1-9, none worked. I have a SparkFun XBee Explorer USB (FT232X USB-to-Serial converter) connected to a USB port on my Raspberry PI 2.
These pins also include an UART serial console, which can be used to log in to the Pi, and many other things. Raspberry Pi Serial Console With MAX3232CPE In addition to the audio, video, network and USB connectors, the Raspberry Pi also has 26 GPIO pins.
