-Protocol
---------
-Signal: Asynchronous, Positive logic, 19200baud, Least bit first
-Frame format: 1-Start bit(Lo), 8-Data bits, Odd-Parity, 1-Stop bit
-
-
-
-Build Firmware
---------------
-Just use 'make'
-
-    $ cd pc98_usb
-    $ make
-
-Then, load the binary to MCU with your favorite programmer.
