Sitting next to one :)

Interesting. I've always had my terminals set to 7 bit space parity -
software needs from many moons ago - but setting it to 8N shows some
interesting things going on with 'display controls' enabled:

Compose key plus keypad:

00 = <NUL>
11 = nothing
22 = "
33 = 3
44 = D
55 = U
66 = f
77 = w
88 = HTS (horizontal tab stop?)
99 = '99' stepped like a fraction.

Mixing keypad and keyboard keys results in a beep and end of sequence. With
parity set to 7S I get slightly different results, but then a lot of compose
sequences don't work with 7S.

Anything else just give me a shout :)
