Making a serial multiplexer (new driver)

[Luís Vitório Cargnini]

Hi i need to write a driver that must multiplex an serial channel my
driver will have  3 interfaces and i must communicate with another
interface  (midleware) like /dev/ttyS2 for example, how could i write a
driver that will communicate with my existing uart ???

i have a component that could be multiplexed in 3 logical channels throw
my single physical channel that are accessed with a normal serial
interface using uart, how could this be possible ?
this is necessary to be transparent to software user level.
