      dterm is a simple terminal emulator, which doesn’t actually emulate any
      particular terminal. Mainly, it is designed for use with xterm and
      friends, which already do a perfectly good emulation, and therefore don’t
      need any special help; dterm simply provides a means by which keystrokes
      are forwarded to the serial line, and data forwarded from the serial line
      appears on the terminal.
