XModem is a simple as a protocol as you can get, it really shouldn't be
too hard to implement from scratch using C code as an example.

Also, as slow as floppy drives are, transfering files over a serial line
is going to be much, much slower.  Simple protocols like XModem are
very inefficent at high baud rates on slow computers.  It maybe more
convienent, but it's going to be much slower for all but the smallest
of files.
