I need to redefine the carriage return key on my IBM PCXT.  The standard
hex values generated when the carriage return is hit is 0D 0A.  That is
a carriage return and a line feed.  What I need is 0D 0D 0A.

This may sound a bit strange, but it really is necessary :-).

PC-DOS ver 2.00 allows binary level redefinition, but I can't figure out
how to get the silly thing to do it! 

I am driving a Decitek tape punch that performs ascii to baudot conversions.
The tapes will be feed into a system that requires each line to be 
terminated with ascii 0D 0D 0A.

I have looked at several programs that allow redefining the keyboard, but
they all allow only key substitution or macro generation.  None of which
will allow me insert a 0D in the sequence generated by the carriage return
key.

HELP!

I am not a programmer (yet!) so please be specific in any help you can give
me.  Thanks in advance.
