[GreenKeys] TTY emulator for iPad

[Dave Horsfall]

I'm thinking of writing a TTY emulator for my iPad (and it's probably 
already been done), but what things should I consider?  I know about USOS, 
auto LF after CR, suppress multiple LFs (all optional in a stunt box), 
different alphabets (inc. WX) etc, but what have I forgotten?

I'll probably never finish it, but it ought to be fun.

Thanks.
