Found a mention that MSDOS and MSKermit (the DOS version) are
being used in the International Space Station. :-)

As per the usual the so-called "Kermit Team" are trying to make
it appear that _their_ K95 Windows version of Kermit is on the
space station, it's not, it's on the ground.  The MSDOS version
is actually on the station. LOL! These guys really annoy me
(obviously). :-\
