I am looking for a device that can connect one RS232 port (TX and RX) on
embedded processor to one of several devices with serial ports and can be
controlled by a couple of I/O bits on the controller. Can this be done?
Any enlightenment will be appreciated.

Yes. An analog multiplexer can be used to mux the RS-232 level, or a
digital multiplexer to mux the logic level.
