  Now that I think of it I don't have ID reading implemented in my 16c84
programmer yet. I think you can do it this way(I'll try it myself this
afternoon):

  Do a Load Configuration to get the PC to 0x2000
  Send it some data(0x0000)
  DON'T do a Begin programming
  Do a Read Data
  increment address
  Read data...

  I think this should work, but I need to try it myself.
