OK, well a quick way might be to add 'colour = "red";' before the 'if'
in sandbox_serial_ofdata_to_platdata(). It causes tests to fail, but
the output will show the ANSI characters. I think it is doing what you
say, since the escape shows up as %1b. I suppose that supporting ANSI
colour codes would be too much of a pain?
