If he was using 1.5.2 or 2.0, then the constants should be in TERMIOS
instead.

There was a release which had a crippled set of constants in termios,
but I can't remember which one it was/find it.

At any rate, all the constants mentioned are in termios on the systems
I have access to in CVS at present.

Cheers,
