According to "Palm Developer Guide, Palm OS Platform, Rev. F [page]
39", the following devices will send these values;
DEVICES: Treo™ 650, Treo™ 680, Treo™ 700p, and Treo™ 755p smartphones,
Tungsten™ T5 and Tungsten™ E2 handhelds and LifeDrive™ mobile managers
VALUES: Power notification == 0x0008. Serial notification == 0x0040,
USB notification == 0x0010
Further discussed at "Palm Developer Guide, Palm OS Platform, Rev. F
[page] 287".
I believe the UserDataP doesn't point to anything. Instead, the value
is passed cast as a pointer. Casting it back to UInt16 should give you
the correct value. A quick test would tell you.
