Redirecting COM ports to multiple hosts?

I have two applications that both need to run at the same time and also need to redirect the output from the local COM port.  Whichever application runs last wins at the moment.  Is it possible to redirect the output from a single serial port to two different terminal sessions?

COM ports don't share well on their own.  There are a number of software tools one can buy that will manage the sharing for you.  If you are a programmer and you want to do something special (like let both apps use the same data one has requested), you might want to try creating a separate thread that reads the data from the COM port and puts it into a common readable location (memory, registry, database, file, etc.) for the application(s).  It is not that hard to write, but it does take some thought.
