We recommend using a free program TeraTerm. To configure TeraTerm for use with any SLCD development kit:
Start the program, then choose:
Setup -> Serial Port…, then set “Baud rate” 115200 (all other defaults are OK).
Setup -> Terminal… -> Newline, the set “Receive” to CR+LF, and then check “Local echo”.
In the main window, hit Enter and you should see the “>” prompt.
