By default, all configurations use UART0 which connects to the USB VCOM
on the DEBUG port on the TM4C123 ICDI interface:
UART0 RX - PA.0
UART0 TX - PA.1
However, if you use an external RS232 driver, then other options are
available. If your serial terminal loses connection with the USB serial
port each time you power cycle the board, the VCOM option can be very
painful.
UART0 TTL level signals are also available at J3 (also at J1):
DEBUG_TX - J3, pin 13. Labelled PA1
DEBUG_RX - J3, pin 15. Labelled PA0
Remove the jumper between pins 13-14 and 15-16 to disconnect UART0 from
the TM4C123 ICDI chip; Connect your external RS-232 driver at pins 13
and 16. 5v, 3.3v, AND GND are arvailable nearby at J10.
