I was kinda surprise that HyperTerminal is not available anymore in Windows Vista. No problem, I rebooted my notebook to Ubuntu and fire-up minicom.

1. By default, minicom is not installed in Ubuntu, so you need to install it first.
   sudo apt-get install minicom
2. Find the name of your Serial Port
   dmesg | grep tty
   In the output look for something like "tty". The output in my case is like this:
$ dmesg | grep tty
[ 17.341823] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
