Cu forks into 2 processes, one that reads the remote tty line and
writes to the controlling terminal and one that reads the terminal
line and writes to the remote.  Most versions leave the process
reading the remote tty running during ~! or ~$ escapes so it is
impossible to use any kind of file transfer protocol.  If you
have kermit set up for dial-out on your system you can either
use it's own native protocol or shell escape and redirect to
the tty as mentioned above.
