Perhaps you could try an Os/2 program or Rexx Addin Function which
would open the pipe for you.  Then you can read and write to it
from a DOS VDM.  I believe I saw a Rexx Demo called Server.cmd which
opened a named pipe for use by other programs.  I have successfully
read from an OS/2 named acknowledged pipe using a DOS VDM written
in GWBasic.  The Rexx Server is easy to start.  Try locating a copy of 
RxUtils package.  This could work?
