In the late 90's we used Kermit running on a IBM-AT clone in my first
digital electronics class. We used
it to download binaries from a DOS-based 68HC11 assembler to a development
board.
Currently I have the Windows and Linux versions installed on my "Rosetta"
machine - a PC loaded up with a bunch of different interfaces and network
connectors to talk to my various machines. I haven't had the chance to use
it yet - I'll probably need it when I try to fire up one of my old Sun4
machines.
