    The SIM800L has a UART interface. Select one of the UARTs on the TM4C1294 device to connect to the SIM800L. Look at the example project:
    C:\ti\TivaWare_C_Series-2.1.4.178\examples\boards\ek-tm4c1294xl\hello
    Note that this example is using UART0. If you are using an EK-TM4C1294XL Launchpad, UART0 is connected to a virtual com port. You should pick UART1 or UART2 instead. If you need to use multiple UARTs on the device, you may find it better to call the TivaWare functions directly instead of using the uartstdio.c utilities. Look at C:\ti\TivaWare_C_Series-2.1.4.178\examples\peripherals\uart\uart_polled.c for a simple example.
