Unprotecting I/O above 10 bits

I wanna do "outb(0x3000,0xff)". How do I do this under SCO or
any other 386 unix from a user program.
I have routines that go into the GDT, then TSS I/O bitmaps to clear out
protection on 0x000 to 0x3ff but thats it (the I/O bitmap only covers
that range).
Thanx
Rick
