On the PC side, a terminal application is needed. A terminal application connects to a COM port and

displays everything received and also allows sending data from the application (via keyboard and

sending a file). There are a few good terminal applications:

 TeraTerm (which is recommended), http://sourceforge.jp/projects/ttssh2/files

 PuTTY, http:///www.chiark.greenend.org.uk/~sgtatham/putty/

 Terminal by Bray, http://sites.google.com/site/braypp/terminal

 RealTerm, http://sourceforge.net/projects/realterm/files/

Download and install the selected terminal application. The next step is to configure the application.

Typical configuration settings are selecting COM port, setting bit rate (for example 9600 bps), set if

parity is used and number of stop bits. Flow control is another setting that is common. Select None for

this setting. Other settings require either additional hardware or software support.

For TeraTerm, select New Connection in the File menu. Select the COM port that appears when the

FTDI UART-to-USB cable is connected to the PC. Click OK. The screenshot below illustrates the

dialog window for setting up a new serial connection.

To set the bit rate and other relevant settings for the serial channel, go to Setup menu and select Serial

Port. A dialog, like illustrated in the screenshot below, opens. Make sure Flow control is set to none.
