[Linux-fbdev-devel] How to output shell on 2 devices

[<chr...@ph...>]

Hello,

We are currently porting ARM Linux 2.4.2 (I know it's an old kernel...) on a board like the Assabet one.
I have written the framebuffer driver based on the sa1100 one.
It seems to work well since I got the Linux pinguin...And Busy Box is starting well...
...but I can't manage to output the shell on boh LCD (fb0) and serial line.

In fact all is output on the serial line (ttyDW4). I want to control the shell with the PC (through the serial line) but I want also things to be output on my LCD.
So in fact I would need to redirected to my LCD (fb0) all the data which come in and come out from the serial line, from where I command the shell.

Can someone explain me how to do that ?

And what about if I want to use the PC keyboard though the serial line without output on the PC itself (ie no characters output to PC but input ones taken into account)

Here my list of devices (ttyDW0-4 are our serial driver):

 crw--w--w-    1 root     root     5,   1 Oct  3 17:21 console
crw-r--r--    1 root     root     29,   0 Oct  3 17:25 fb0
crw-r--r--    1 root     root     1,   3 Oct  3 17:23 null
crw--w--w-    1 root     root     5,   0 Oct  4 10:44 tty
crw--w--w-    1 root     root     4,   0 Oct  3 17:21 tty0
crw-r--r--    1 root     root     204,   5 Oct  3 17:19 ttyDW0
crw-r--r--    1 root     root     204,   6 Oct  3 17:20 ttyDW1
crw-r--r--    1 root     root     204,   7 Oct  3 17:21 ttyDW2
crw-r--r--    1 root     root     204,   8 Oct  3 17:21 ttyDW3
crw-r--r--    1 root     root     204,   9 Oct  3 17:21 ttyDW4

Have a nice day.
