[Elecraft] K3-P3-TR Logging Program

[Lew]

Just received the P3.  Connected up the K3-P3 and logging computer with TR working. I read and understand the difference in rate between the baud rates between the K3 and P3 (38,400) and the P3 and whatever the computer program needs. ( in this case 4800 as that is the fastest rate TR will take).  When I query the P3 with the K3 utility it reports the speed for the P3 at 4800 after I set it for that speed on the P3.  The TR program doesn't communicate with the P3 even though the rate  is correct.  When I turn off the P3 and reset the K3 rate to 4800 it works perfectly.
    A few questions:
     1) Does the P3 emulate the K3 as in using the Kenwood protocol for communication or is it a new animal that maybe TR doesn't recognize?
     2) Anybody have the K3-P3-TR logging program functioning all together?
     3) What am I not seeing wrong here?
     4) Yes I know I should get a non-DOS logging program but my current configuration really works well and I hate to fix it because it isn't broken!
   Tnx-  73 and I remain,
