Serial console terminal installation
Many serial console terminal programs are available, either as commercial software or from open source
communities. In this user guide, the examples show the Putty terminal emulator running on Windows 7. Putty is
an open source stand-alone application that runs on multiple operating systems. Download and uncompress the
software package from http://www.putty.org, and then run the executable file.
For more information about Putty, see http://www.putty.org.
