Mike,

The jumpers on P4 control the logic of RTS and DTR.  The jumper is labeled as:

  1 * * 2
  3 * * 4
  5 * * 6
  7 * * 8

looking at the paddle board with the DB-9 to the left.  Jumpering pins 1 and 2
allow RTS to toggle freely.  Jumpers across 3 and 4 tie RTS high.  Jumpering
pins 5 and 6 allow DTR to toggle freely while jumpering 7 and 8 tie it high.

Steve's problem is pins 3 and 4 are jumpered.  The default settings on the
paddle boards are for 3,4 and 5,6 to be jumpered.  If he moves the jumper on
3,4 to 1,2, it should work.

This is all explained in the tech manual.

Mark
