The KiCAD files are updated to version 1.1. What is build and tested, was version 1.0 and some connection issues were found. These were corrected, but no new boards were made and tested. I expect they work Ok, but have no plan to test this.

The fixes are:

- The Rx, Tx serial lines between the Arduino and MAX232 were crossed. As the AltSerial library uses fixed lines, it was not a simple operation to fix it in the firmware.

- The Rx and Tx lines were also crossed between the MAX232 and the DE-9 (J4).

- The capacitor C6 is moved from the PR signal to the +6V power supply line.

- The DTR line is now connected to the HW Handshake Patch block.
