This example demonstrates how a PIC microcontroller with a single USART peripheral can be connected to up to three USART devices; say a GSM, GPS and maybe a raspberry PI.
The USART ports are multiplexed using 74HC151 to the PIC RX pin and 74HC138.
Hardware flow control can be used to control device communication.
