Hi guys,

I'd like to use one of the serial ports on my embedded device from a
module (so I can write an input driver for the buttonpad on my PDA).

I need to be able to set the data type to 8O1 and set the port speed,
and send and receive data.

Whats the proper way to do this? Ideally I'd want to prevent userspace
being able to use the port which has the keypad connected, but not touch
the other two ports.

Thanks,

-Ian
