Hi Greg,

thanx for the reply!

No i don't have any weird h/w, it's just that
i wanted to learn how to write device driver
modules in linux. I chose a serial driver b'cos
a lot of people have told me it's the simplest
to implement.

Yes.  But why would you want to do that?  Do you have some wierd serial
port hardware that Linux doesn't support?

thanks,
