minicom requires lrzsz to do x/y/z-modem. If you try to do a file upload via minicom on a system that doesn't have lrzsz, it doesn't say something like "no handler for this protocol" or "install lrzsz", it prints out a dot every few seconds, JUST LIKE ONE MIGHT EXPECT A REAL UPLOAD TO DO! This is incredibly perverse and confusing, enough to count as a real bug not a misfeature IMV.
