Tera Term

This is recommended for end users, not maintainers and developers. Tera Term allows for configuring the receiving serial port of a user's computer to match the transmitter's settings and can be downloaded here.

Example

Connect the Arduino Uno R3 to your computer via USB. Open Tera Term. Select Serial and the corresponding device port. Select Ok.
