Hello evrybody,

I am trying to communicate with arm7 using paralel port in user space.

Using parallel port pin programming (source from sourceforge.net parapin programming).

Sometime I can able send and receive message successfully, some times system Hangs.

My PC uses the Fedora6 and kernel version 2.6.21.5. Can any body give me an input why system hangs.

Your any input is greatly appreciated. Thanks in advance.
