I don't have any of the DOS emulators for UNIX but I am sure that many
people will suggest one.  As for inter-process communication, I doubt
if that specifically exists but here is how I would do it.  Use mknod
to create a UNIX pipe (or 2, input and output).  The DOS program can
open this pipe as a file and read and write to it.  The UNIX process
can do the same and you have your IPC.

As I don't have (or want) DOS under UNIX, I may be off base on this and
welcome comments or corrections if there are better ways.
