Easy answer first.  P mode is unique to Explorestars.  It is useful if you have a virtual polar alignment from doing a 2 or 3 star alignment.  P mode correct the pointing position in both ra and dec 5 times per second, each time applying pointing corrections needed due to pa error, tip, tilt, and ra home error.   

T mode in explorerstars is the mount running with only the ra axis moving at the correct sidereal rate.   This is equivalent for tracking in ascom, and should be for any other driver system such as the asiair.
