Well, Carl, you don't mention changing out the serial card itself.  I
don't know what an "ALR" brand is, but if the serial card is
replaceable, or you can add another, I would replace the cards with
new ones (or with ones from PC that work).  Maybe not much help, but
another idea to try.  BTW, you don't mention whether you have other
ALR machines that work (obviously, if not replace 'em).
