Erlend Nagel has exonerated Kermit, but you are quite right about the
primitive file transfer protocols like Xmodem. However, if you want to
experience the full joy of characters like DC1, DC3 and SYN, you should
get good mileage by setting your modem for software, rather than
hardware, flow control, turning off compression and error correction,
and then transferring binary data. The modem should have a number of
interesting configurable options for how it reacts to X-on and X-off
(DC1 and DC3) and, whilst the mathematics of permutations say that you
can find the correct setting in N or less attempts, Murphies Law (and my
personal experience) dictate that your number of attempts is always at
least N+1.

Chris
PS. Nobody with any sense of self-preservation ever changes the init
string of a functioning modem, so don't do this at home!
