Connect to the serial communication channel from linux using PuTTY

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

The LaunchPad includes a pre-programmed MSP430G2553(datasheet: 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 page 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/ttyACM0
I haven't seen the LaunchPad USB serial working yet, so I'm trying to figure out whether the problem is with my Linux install or with the LaunchPad.

How can I read the data from the LaunchPad demo in Linux?


I am on Ubuntu 12.10 64-bit

I do not have schematics, and the hardware to look at.

Sometimes such boards also needs some steps to setup the communication. There is also the probability that nothing is sent from the board? Did you try with a scope?

How does the setup looks like? is there an usb-RS232C dongle involved?
