I use a USB (FTDI) to serial 3.3V cable connected to a HUB. It shows up as COM6 in device manager. When running the nxp_lpcxpresso_812_periph_uart_rom_int example I could transmit text from the LPCXpressso board to a terminal but could not send text from the terminal window to the LPCXpresso board. Will try with a new FTDI cable.
LPCXpresso comes bundled with an LPC800 driver library, and a UART demo program which can send/receive to a terminal program. I suggest you find a working board, and run the example to test your serial connection.
