switch tty to raw mode, and there will be no signals. see my 
iv.rawtty2, for example.

this is hightly dependent of the actual terminal emulator. in 
real world, it is enough to support xterm mappings, rxvt mappings 
and "Linux" (this is "real" console) mappings. xterm and rxvt 
mappings aren't really conflicting (much). again, the messy 
iv.rawtty2.ttyReadKey may give some clues.

of course, "best practice" is to use termcap/terminfo, but this 
is even bigger mess! ;-)
