Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

The ARM board computer I am currently working on does not have a working framebuffer terminal due to a buggy kernel.

I have managed to follow the instructions at https://help.ubuntu.com/community/SerialConsoleHowto to get the login prompt up on the UART port.

However my USB-UART adapter has a broken input line.

Thus I want to know how I can connect the output via ttyS0 with the input via tty0 (connected to the USB keyboard) so I can interact with my computer.

I wonder if it is possible to echo tty0 into ttyS0?
