I think (but I am not sure - I've never done this) that you might be
able to use a program called OS2You (available via anonymous FTP from
the OS/2 archive on ftp-os2.nmsu.edu).  But basically, OS/2 is not
set up to support serial terminals.  All you'd ever get is a command-
line interface.  This is not what you really want to see with a
graphical operating system like OS/2.

The best option by far is to buy an Ethernet board for each of your
PCs.  Check the most recent issue of PC Magazine for a review of
zillions of Ethernet boards.  We're talking $100 for a cheap but
adequate board.  Make sure you get it with NDIS software, if it's
not a board that's comes with a driver in IBM's LAPS package.  In
theory you could do it via serial ports, using the SLIP (Serial Line
IP) driver included with the TCP/IP package, but (a) the performance
will be terrible; and (b) it's not worth the trouble since Ethernet
boards are pretty cheap.

You can do that using IBM's TCP/IP package.  The Base package alone
will let you do transparent printer sharing, copy files back and forth
("ftp"), and get a command-line login on other machines ("telnet").
Add the NFS package and you can share files.  Portions of other
computers' disks appear as additional disk drives on your machine and
are accessed over the Ethernet.

For the sort of network you're considering, X Windows doesn't fit in.
X Windows is a protocol (developed for Unix machines, originally) to
allow a program to run on one machine, but display (and get keyboard
input) from another machine.  This becomes very useful if you've got
a Unix host on your network.  Then you can run X programs on the host
and have them display on OS/2 machines - i.e. use the Unix as the
powerful back-end and the OS/2 machines as display front-ends.  The
reason this doesn't work for an OS/2 network (yet!) is that there
are no programming tools to allow one to develop X Windows programs
the actually run on OS/2 (i.e. the core program both runs and can
display on OS/2 systems).  We hope this situation will change soon, but
for the time being, if you don't have X applications on a Unix box
that you can access over the net, the X Windows package will do you
no good.

On further consideration (and actually _reading_ what you wrote):  X
Windows might not be useless IF Desqview/X can serve as an X Windows
client (confusingly, in X terminology, the "client" is the machine that
runs the core program; the "server" is the machine that runs the
display front-end).  The IBM package is an X "server" (i.e. display
front-end).  Desqview/X can certainly act as a "server" also, but
whether it also has "client" capabilities (i.e. can run a program that
displays elsewhere), I don't know.  If it does, then you could run
client programs on your Desqview/X PC and have them display on your
OS/2 machine.

You're very welcome.  For further gory details on TCP/IP under OS/2,
see the document "/pub/os2/2.0/network/tcpstart.txt" on the archive
server ftp-os2.nmsu.edu.
