发帖数: 7227 | 1 hi my atmel board has rs232 and rs485 port, i connected the serial cable
from my pc to it, in com1 for hyperTerminal i see nothing.
there's another debug port in the board, if i plug in the cable,
hyperTerminal works.
so confused, thought rs232 works with serial cable ? | G*****h

在grub的配置和kenel启动时的参数里设置。
具体的配置忘了。google可以找到很多 search "linux serial console"
