Both of these changes are implemented on all of my boards.

- I use a 10uH, 0.1uF low pass filter.
- For the reset I have a 1N4148 from the reset pin to Vcc. I also include
a position of a 0.1uF cap from /RESET to GND. (NB If you use the
0.1uF from /RESET to GND the /RTS on close reset will not work
reliably).
