I bought the MOD-RS232 uext module for the imx233. I do not see the /dev/ttySP0 anymore. This is my /proc/tty/drivers

root@debian:/# cat /proc/tty/drivers
/dev/tty             /dev/tty        5       0 system:/dev/tty
/dev/console         /dev/console    5       1 system:console
/dev/ptmx            /dev/ptmx       5       2 system
/dev/vc/0            /dev/vc/0       4       0 system:vtmaster
ttyAM                /dev/ttyAM    204      16 serial
pty_slave            /dev/pts      136 0-1048575 pty:slave
pty_master           /dev/ptm      128 0-1048575 pty:master
unknown              /dev/tty        4 1-63 console

I am using the standard debian distribution provided on the website.
root@debian:/# uname -a
Linux debian #11 PREEMPT Mon May 21 10:27:52 EEST 2012 armv5tejl GNU/Linux

Does anybody has an idea why the /dev/ttySP0 serial device is not displayed for the uext module? Now I can not use the serial module in any applications.

Can be closed. Fixed myself. It is just strange that the standard debian kernel does not have the proper drivers.
