[ECOS] Serial Port , Raw Mode using cyg_io_read

[Annamalai Prakash <aprakash@tataelxsi.co.in>]

Hi List,

 I am working on ARM920T (Integrator) and ecos. I have configured my kernel 
with posix and Serial device drivers.  following options are enabled in my 
config file.

           CYGOPT_IO_SERIAL_SUPPORT_NONBLOCKING 
    CYGPKG_IO_SERAIL_TTY
     CYGPKG_IO_SERIAL_TTY_TTY1
    CYGPKG_IO_SERIAL_DEVICES
    CYGPKG_IO_SERIAL_ARM_INTEGRATOR_SERIAL1

       I want to configure my serial port in RAW mode.  i think ecos supports 
two serial port drivers (raw and tty driver). Is there any explicit option to 
specify  for RAW drivers.  I tried to disable (CYGPKG_IO_SERAIL_TTY_TTY1) 
option, i wasnot able to read/write anything from serial port even opened 
successfully.

       I tried to use OPEN call also. i got compilation error due to 
unresolved symbols `O_NDELAY' ,`B115200' ,`CLOCAL' ,`CREAD' . i have 
decleared terminos.h ..

Any lights to move furthur..

Thanks
Prakash
