Wow that was not an issue I was expecting!  I assume it's not an issue with BBS software written for modems, as there was always some delay between bytes, but for a telnet BBS like Mystic there could be an assumption that the multi-byte characters would arrive all at the same time (in the same TCP packet).  Interesting edge case.

That's some good detective work!

I have such fond memories of XT machines, but I do find using them today to be so much more painful than I remember.
