Using PuTTY for Serial
PuTTY can replace HyperTerminal for serial communications. It provides logging, a large scroll back buffer, and many other features. You are probably already using PuTTY for SSH and Telnet, but you can also use it for Serial TTY console connections.
If you use an Apple Mac computer, refer to: Mac's and serial TTY's.
