Note that while the Arduino environment now (from version 1.0) includes the FTDI drivers, you will need to install them manually for Coolterm to be able to speak over the USB connection as a serial connection. It almost works without them, only not quite! | Note that while the Arduino environment now (from version 1.0) includes the FTDI drivers, you will need to install them manually for Coolterm to be able to speak over the USB connection as a serial connection.
