NB: The example code below may fail to work properly if all of the
below are true.
* You're using a real, physical terminal
* Connected to a real, physical serial port (not a pty)
* Without flow control
* And the terminal requires "pauses" to allow time for the
terminal to execute the some commands before it can accept
further data.
The functionality that is added by tputs() is to insert "padding"
(typically extra NUL bytes) before/after certain certain terminal
operations.
What I _don't_ know at this point is what happens if you're using a
terminfo description that specifies padding, but you're not connected
to a physical terminal via a real serial port.
