Hello,

I am using a PowerPC MPC5200 from Freescale (STK5200-Board), ELDK 4.2 from DENX,
Kernel 2.6.34-rc5.

My Kernel is running fine. The console output is coming over the device ttyPSC0. In future I want to login over telnet. So I deactivated the Kerneloption to output the console over the UART device.

Now I want to read and write to the RS232 interface from a program.
But when I try to open the device ttyPSC* I get the follwoing error:
"unable to read portsettings : Inappropriate ioctl for device"

What does this mean ? How can I send and receive Data to/from the UART ?

Is the error reported by a program you've written, or it's something standard?
