Named pipes, which are created via DosMakeNmPipe, look like part of the 
file system and are supposed to be readable/writable from other OS/2 or
DOS applications via open/close calls.  Your OS/2 debug application
should create the pipe by calling DosMakeNmPipe specifying a unique
name in the form "\\PIPE\\your-name".  It then should issue a 
DosConnectNmPipe which will block until a "client" program (DOS or OS/2)
issues an open on the named pipe.  Your DOS program can treat the pipe
as any other file and read/write from/to it.  Your server program should
issue DosRead to get the data written by your DOS client.

I think this should give you an idea of the process but before implementing
I recommend you read the OS/2 Programming Ref. Guide for details on the
actual calls.
