I've connected up a PL2303 USB-to-serial adapter from UART0 to my Macbook Air (OSX10.9) and used ZTerm as the terminal emulator set to 115200 baud, 8 bits, no parity, 1 stop bit. But all I get is garbage when I boot my A10s-4GB Android board.
I've tried the same from Windows 7 using PuTTY with the same result.
I can adb shell to the board and run "busybox stty -a -F /dev/console" and this tells me 115200,8,N,1 are the right settings.
I've got TX,RX,GND connected and, yes, I've crossed TX and RX.
What am I doing wrong? Thanks!
Are the voltage levels correct for that?

Spot on, John. My PL2303 USB-to-serial adapter also had an RS232 level-shifter in it. Silly me. I hacked another cable that does TTL voltages and, hey presto, everything worked with 115200,8,N,1.
Hoorayyyy!!!
