| - | === Setup PuTTY === | + | === Linux === |
| + | From a command terminal, run: "sudo dmesg | grep tty". This will print out a list of system messages related to active TTY (serial line) ports. Usually you will see entries for ttyUSB0 and ttyUSB1. Port ttyUSB1 usually seems to be the one that the board is connected to - if that fails to work then try ttyUSB0. If it fails you will get a failed to connect error when you first open it. And, remember that when you run putty you have to run it as ''sudo putty'' or you will get a permissions error. | ||
