Testing UART Function
3.3.4.
The VIA Smart ETK UART function supports TX/RX communication with other devices.
The COM port of the VAB-630 board supports RS-232 mode.
The first step is to connect the host machine to the COM port on the VAB-630 using an
RS-232 cable. Next on the host machine start a serial communication program such as
Putty, GtkTerm or Minicom with the same serial port setting using the appropriate serial
device.
