I need to write something that multiplexes data from a serial port device file (/dev file) so that multiple applications can share the data on that port. All of the apps need to be able to read and write to the port.

Can anyone recommend the right path to write this thing? Can it be written in user space or will i have to write a driver to do it? Is there a better list to ask this question on?
