Cant read from Serial port

[prashanth]

Hi every one, I am using an ARM development board from cirrus logic
(EDB9302).
My program uses a serial port, i tested my program on my PC, which
runs on Intel chip and its running fine.
The same program when executed on ARM board (using the second
serial port available on board), the program can write data to the
port but it cannot read data from it
(which i figured out by connecting it to a serial port on PC).
Any idea why??

Details about the board: http://arm.cirrus.com/files/schematics/edb9302

with regards,
Prashanth

Wrong/missconfigured hardware handshaking?
