This makes sence, for portability reasons there might be helpful
not directly use the fifo-s from user side but through special function
calls to do the same things for input and output.

Since my time is up for now I'll use tty calls directly for now and make
for DOS another routines using rs232 with dzcomm. I think that at some
time I'll return to the portability of dzcomm. This is very good library
to use with DJGPP.

Did not work, rv stays always -1. I looked the driver wrapper layer
functions and saw that there might be some flag problems too. Since my
time is up I did not dig deeper.

If You get this working it will be very helpful for any newcomers to have
such program as an example for DOS and for Linux.

Many thanks ...
