The driver will reliably produce the codes it has been told to produce by the shell or by the user tells, using ioctl or stty commands. This reminds me of a “D’Oh!” moment aeons ago, when I suggested to Mark Horton that TERM should not be an environment variable. It should be a settable property of the tty. Mark agreed, but neither he nor I felt like going to bat for it back then. This architectural mistake should still be fixed, IMHO. Perhaps the modern world of 2012 would be able to absorb this change, if implemented properly. BTW, I did significant work on the Fortune Systems tty driver in (cough) 1982-1983. * Horton, Mark.
