Serial communications sensitivity

Hi!

Thanks for a splendid project and tool for the 6502 computer! I have tried it and finally got it to work after some required tuning of the Arduino program read delay (READ_BUFFER_DELAY).

As a tip for other people having problems, it may help to tune the Arduino SW read delay. I've found that no other tuning of baudrates (config files and hardcoded in Arduino SW) seems to work. However by increasing the READ_BUFFER_DELAY to 40ms, it worked perfectly for me. The original value of 20ms and also 30ms resulted in a large number of retransmissions, and corresponding timeouts.
