-In this four-part tutorial we will build a Raspberry Pi that will be able to present itself as a serial modem to a client computer which will enable easy connection to Internet using their pre-existing serial port on any Windows 3.1/95/98/Me and any other operating system with built-in support for [[wp>Point-to-Point Protocol|PPP]]. In other words we'll be using a Raspberry Pi to translate a serial connection into an Ethernet connection. When all is said and done, your Windows 3.1/9x computer will be fooled to think that it's calling an actual [[wp>Internet Service Provider]] and establishing an Internet connection with them. This will in fact just be your Raspberry Pi telling your computer what it wants to hear, and is just providing access to the Internet using your pre-existing Internet connection.
+Anyone remember the good old days of dial-up connectivity? Well, back in 80's and 90's, computers connected using a dial-up modem, and the only thing computers needed was a serial COM port for communication, which was included virtually with every computer (USB didn't exist back then!). Nowadays every computer sold has some sort of Wi-fi or Ethernet connectivity, and our old legacy computers are just left to rot! Well, I'm planning on changing that! Why? For fun, of course! :-D

 The [[.:virtual_modem:script|Virtual Modem script]] will not only allow you to connect your old computer to the Internet, it will allow you to use the serial connection to login to the console of the Raspberry Pi or fake [[wp>Bulletin board system|BBS]] phone calls for example. The script was designed to be modular, and will allow you to assign your own Linux scripts to specific phone numbers, accessed with standard Hayes "ATD12345"-style commands. I will be writing specific tutorials about these functions at a later time.
