I am able to run own version of resource managaer for serail port - developed not using DDK. The platform in which in am
 working is Freescale power pc, now i want to know what i need to do extra to ensure PPPD works in similar way, as if i 
am working on serail driver supported by freescale. 

As i see i need to set some attributes realted to device, i dont have any idea about that, and at same time the OS build
 in my target is not full fledged (it is there to extent required). Please help me what extra i need to do as i am 
getting following message when i typed PPPD /dev/example1....example1 is my new serail device 

# pppd /dev/example1
pppd: tcgetattr(/dev/example1): Inappropriate I/O control operation

I already appended this question in my old subject ..since this is a seperate question i thought creating  a fresh would
 be right thing 

Thanks
Ravi
