INT 16 provides 3 functions on the PC

        AH=0  read char
        AH=1  char avail. ?
        AH=2  check shift status

On the PS (or at least on the model 80) several new functions have been added,

        AH=3
        AH=5
        AH=16
        AH=17
        AH=18

They are not documented, but I really need to know what they are for - in
particular AH=17.

The reason is that I am working on a memory resident spelling checker, that
does not function with some word processors (Word 4, Microsoft Works and
Diaplaywrite 4) on a PS, due to the fact that these undocumented functions
are then used.

If you have any information, PLEASE send me mail (frisk@rhi) - I will
summarize if I get any useful replies.
