Actually, I think he was refering to the required 2.5mm to 3.5mm stereo headphone adapter necessary to plug the Total Remote transmitter module into a 19xx series iPaq.

Radio Shack, part number 274-373:

This works like a champ on our 1910. Controls our Sony DVD player from over 65 feet away! Of course, as was pointed out, you do need the full retail Total Remote package which includes the audio transmitter module. Otherwise you'd have nothing to adapt. :)
