subject: CD Changer eject/retract

I need a solution to a problem I have, REXX will be fine, or Borland C++ (4.5 
dos, 2.0 os/2) if someone is adventurous, but I think REXX will be easier.

I have a Panasonic 5 CD changer (ATAPI). Currently I have to press the various 
eject buttons to change CD's, and then push the tray back til it kicks in and 
retracts. I know it can be ejected/retracted via software control as the 
windows utility is supposed to do it (but the utility goes bonkers under os2, 
among other problems). I also have a OS2 CD player program that is able to 
eject the CD tray it is playing (only works with the default audio device 
though), but it can't cause the tray to reload. 

Anyone got any ideas how to do the eject/retract? Appears to work with the 
drive letter (each tray is a different drive letter)...

All I need is something to pass the appropriate drive letter and it will
eject/retract it, ie:

EJECT H:
RETRACT H:

etc..
