I don't know of any standard way to do this in OS/2 (what I mean is that I am
pretty sure that it is not possible with OS/2 alone).

I have written a program called Os2You, that allows you to run ONE OS/2 full
screen session remotely via asynchronous line (by modem or cable).  For those
requiring login facilities and callback, I have written M2Zmodem, which will
do the job, in combination with Os2You.

The program is sort of a Shareware Program.  You may use it for trial, which
is limited to 5 minutes operation each time you start it.  If you register it
the limitation won't be there.  By the way, the program is for the protected
mode sessions, and not for the DOS coffin.

To get more general about the subject, I think it will be very hard to do a
remote redirection software, making it possible to switch between sessions,
and even run PM-programs.  This would be very slow, if you transfer all the
graphics information.  Another idea is to transfer just the system calls with
their parameters, but this would require a very advanced "terminal program",
to correctly translate the OS/2 system calls to appropriate output.

There is another (professional) package, allowing you to redirect ONE full
screen session, but I don't remember the name.  Anyhow it was a very expensive
package, while my solution is very cheap.
