Serial communication set up

I created a serial device (tty0p0) using SAM.
I'm able to write to the device ( I can see the data on
the other side of the null modem cable),
but I can not read any data

SAM also removed read access to /dev/tty0p0,
I did change it using chmod +r /dev/tty0p0, but still no luck.

Is this port some how locked ? (I checked /var/spool/locks and is not locked there)
