查看串口1(/dev/ttyO0)当前的参数,包括波特率、数据位等。 其中speed就是我们想要修改的波特率
stty -F /dev/ttyO0 ispeed 115200 ospeed 115200 cs8
该命令将串口1(/dev/ttyO0)设置成115200波特率,8位数据模式。一般情况下设置这两个参数就可以了,如果显示数据乱码,可能还需要设置其它参数,注意,此种方式只能设置标准的波特率,自定义的波特率是没法设置的。
root@root:~# stty -F /dev/ttyO0 ispeed 115200 ospeed 115200 cs8
root@root:~# stty -F /dev/ttyO0 -a
