How xfree86 handles keys that have four scan codes

[Shiju Mathew <mshiju@xxxxxxxxx>]

Hi,
I have a remote controller on which some of the keys generate four scancode. When I use "showkey"
it
shows all the four scancodes(ctl+shift+alt+f1). But the xwindows(xev)
interpretes only three scancode. But the third scancode seems to be
wrongly interpreted. Could someone help me to configure the xfree86 so
that it interpretes keys with 4 scancode. Or is it a limitation with
xfree86 to interprete keys with four scancode. Please help.

Thanks ,
Shiju
