PuTTY is a Windows program for terminal access to Linux computers.
Today connected Arduino on the PC with Ubuntu, screenshot taken off the his session. Here we can see the correct data coming from Arduino.
When I asked back in Reply #1 what OS you are using I wanted to know what OS is on the PC that the Arduino is connected to. I'm still not sure if you have answered that.Is that the same PC that you were connecting to with PuTTY ?
