TI Launchpad MSP430 on Serial in Linux   General Discussion

The background for question: the MSP-EXP430G2 LaunchPad Experimenter Board User's Guide (Rev. C) in chapter 3.2 states:

The LaunchPad includes a pre-programmed MSP430G2553 device [...]

Press button P1.3 to switch the application to a temperature measurement mode. [...]

The collected temperature data is also communicated via back-channel UART through the USB emulation circuitry back to the PC. The transmitted values [...] can be displayed with any terminal application or the Temperature Sensor GUI available on the MSP430 LaunchPad wiki pagehttp://processors.wiki.ti.com/index.php/MSP430_LaunchPad_(MSP-EXP430G2). The serial communication port on the PC must be configured with 2400 bps, one stop bit, and no flow control to display the values correctly.

I've been trying to connect to the serial communication channel from linux using PuTTY (/dev/ttyACM0, 2400Bd, 8N1), but nothing happens.

Similar results with:

stty /dev/ttyACM0 2400
screen /dev
