Is it possible to use TeraTerm or similar to send or receive characters from the
launchpad board?

Yes. But only at 2400, 4800, or 9600 b/s. no-parity, no hardware
flow-control.

James, I'm going a bit by memory here but if I recall correctly, the LaunchPad board contains both an "emulator" portion and a "target" portion. These two sections of the board are connected by a series of jumpers across J3 and the emulator section connects to your PC via USB.
When you install whichever TI-approved development environment you choose (I installed Code Composer Studio V5 under Windows 7), a USB device is installed called "MSP430 Application UART" and when you bring up your development environment and plug in your LaunchPad board, that device will be enumerated and assigned a COM port number and the debugger USB connection to the LaunchPad will also be installed.
If you keep the appropriate jumpers across J3 installed, TeraTerm will be able to connect to the just installed "MSP430 Application UART" via its assigned COM port number. In TeraTerm you set the SerialPort options to match what you're doing with your MSP430Gxxxx project.
In your MSP430Gxxxx project you will have configured the microcontroller's UART and will have written code to use the UART to send and/or receive.
You can find The "MSP430 Application UART" COM port number on a Windows system as follows: click on Start, right-click on Computer, click of Properties, click on Device Manager, click on Ports (COM & LPT).
Hope this helps.

Also, be aware that the jumpers are different in the rev 1.4 and rev
1.5 launchpads, and the serial driver is notoriously flaky under
Windows and Linux.
