Okay,
  I have NO IDEA if this will work, but try it and see (when you get the programmer).
  You send a "P", On_LSB, On_MSB, Off_LSB, Off_MSB (so five bytes in total).

  The board runs at 4mhz, so the On and Off times are at 4MHz. 

  To run though the PWM output levels you could do something like:

  FOR I =0 TO 255
    SEROUT "P", I, 0, (255-I), 0 ' "0" is a zero
    PAUSE 100
  NEXT

Something like that will will generate a 15.6KHz PWM output that varies in duty cycle.

Let me know if the code works.
