Sure it is. I'd just bodge something together in Perl as a prototype,
safe in the knowledge that I shouldn't be able to crash or corrupt the
kernel.

My RS232 inline monitor has been *very* handy in the past for
debugging that kind of setup. Usually the problem with no data flowing
is a cable (or port!) that's not wired up as expected.
Commercial units are probably as rare as hen's teeth now, but they're
also really simple and suitable for a first electronics project.
(Especially as there's about a fiver's worth of parts in it, tops, and
they seem to sell for ten times that.)
