Check out the following code from graylib, which does just what your
trying to do.
It seams to write to $20000+$vector address
I think that its a workaround because of the way the ti-92's memory
wraps around, but you could use similar code for your pourpose
        movem.l d0-d7/a0-a5,-(a7)

        move.w  #$2700,sr
        move.l  ($020064),old_int_1
        move.l  #int_1,($020064)
        move.w  #$2000,sr

        movem.l (a7)+,d0-d7/a0-a5
