Can't you "cat file > /dev/ttyS0" on the sending end and "cat /dev/ttyS0

md5 on both sides and manually compare the checksums.

If you insist on perl, this look good:

[*] Incidentally, I was doing VoIP before it was called that many years
ago like "cat /dev/dsp | nc remote.host 1337" and "nc -l -p 1337
> /dev/dsp".  Effective and simple :)
