Color Computer RS232 Pak
In 1983, Tandy released a 'Deluxe RS-232 Program Pak' which was designed to allow operation of the Color Computer with a modem. The RS-232 Pak contains a special integrated circuit to more effectively handle serial communications. The chip, called an Asynchronous Communications Interface Adapter (ACIA), overcomes problems inherent in the bit banger design. The RS-232 Pak also contains communications software in a ROM to make the computer act like a terminal for operation with a modem. The RS-232 Pak has since been discontinued, but it is possible to build your own inexpensive RS-232 interface that can be reliably used with modems and terminals.
