Hi all,
I have an embedded Linux board that uses 2.6.21, the console is output
the serial port. How can I set it up so a USB keyboard will be accepted
as input as well as anything received from the serial port and it will
be echoed to the output of the serial port as well. Basically I want to
issue commands either through a terminal program to the embedded board
or a USB keyboard that is connected to the board, but I still want to
see what was typed on the keyboard out the serial terminal. I have
enabled USB HID support in the Kernel as well.
I was told from another message list that somebody might have done this
here about a year ago, but I couldn't find anything in the archives.
Thanks for your help and please CC [email protected] as I'm not a
subscriber to the list yet.

Try booting with console=tty0 console=ttyS0
I am not sure whether this will accept input from both (that's for you
to test), though it definitely outputs to both.

This method doesn't seem to work on my setup since I'm only using the
serial port as the console, and have no frame buffer. I can
cat /dev/input/event0 and get what appears to be scan codes when I press
keys on my keyboard. How can I translate this into specific commands
for my serial console?
Thanks
