This is related to one of my concerns. In the 80s on my Vic20 and 64, I
would download stuff using Xmodem (then Ymodem and Zmodem), which had
various checksumming protocols to ensure that an "A" character didn't
get hit with a piece of static and turn into a "B" character.

When sending files in a homegrown way (especially over a modem!), some
kind of checksumming is going to be required, is it not?
