This UART can be used for boot logging by coreboot, SeaBIOS, or Linux. It also works as a general-purpose UART. Soldering is required to access these signals. Locate the pads for U81 on the bottom of the board near the front edge; the IC is not populated. TX is pin 14, RX is pin 19. The signals are 3.3V (do NOT connect directly to an RS-232 serial port).
