You may have tried this already,  but have you used the DOS-based PS2.EXE
utility to enable the IR (and disable the serial port)?  I don't have a
600X, but on a vanilla 600, this is what I had to do to get the IR port to
work.  (tpctl ought to do this, but it might be easier to set it up with
PS2.EXE and forget about it...)
