Different modes of UART

ms14 has a uart interface expose on the 2x8 router connector. this interface can be act as:

  • Console port to debug the openwrt system inside ms14. refer link here.

or

  • UART interface to communicate to other devices such as a avr daughter board.

to disable UART as a console port, user can comment the related line in file /etc/inittab. And reboot the device. 

root@dragino2-684db6:/# vi /etc/inittab 
::sysinit:/etc/init.d/rcS S boot
::shutdown:/etc/init.d/rcS K shutdown
#ttyATH0::askfirst:/bin/ash --login                        // Comment this line to disable uart as console.
