We recommend using a free program, Tera Term. To configure Tera Term 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.
