using SCC4 on MPC8272ADS

["Landau, Bracha" <BLandau@nds.com>]

I am using the MPC8272ADS with kernel 2.6.10. The kernel is configured to=
 support 4 CPM SCCs, of which 1 and 4 are connected on the board.
I created device files as follows:

mknod /dev/ttyCPM0 c 204 46
mknod /dev/ttyCPM1 c 204 47
mknod /dev/ttyCPM2 c 204 48
mknod /dev/ttyCPM3 c 204 49

If I boot the kernel using console=3DttyCPM3 I see that it uses SCC4. But=
 when I boot with console=3DttyCPM0 and write to the second port using a =
command like "echo hello > /dev/ttyCPM3" I don't see that anything is bei=
ng outputted to the second console.

What am I doing wrong?
