I saw in Reference,Language page in 86duino.com. (http://www.86duino.com/?p=1807) That said abount Serial232 that will send and receive data from COM port (DB9) at rear of EduCake. I try to used Serial232 but it can not use. I used Oscilloscope to measured signal. No signal from COM port.
Please correct this problem.

HI:
I use this code,it can work.

void setup() {
// initialize serial:
Serial232.begin(9600);
}
void loop() {
// if there's any serial available, read it:
while (Serial232.available() > 0) {
Serial232.println("HELLO!!");
}
}

i think you select the wrong COM port,its different then UART port.
in my computer,i use COM 14 to burn program,and my serial232 is COM 20.

The problem in my EduCake is it has wrong BIOS.
My EduCake has BIOS Guava0.9 that is for 86Duino Zero or ONE.
After change my BIOS to GuavaCake 0.9. Serial232 OK.
Step 1. Prepare SD card for SysImage Installation (Windows)

Step 2. Read "86Duino SysImage User Guide" to change BIOS
