ABSTRACT:
An interface apparatus and method is disclosed which allows communication of digital data messages between a first type of data terminals (10 and 65) employing a message protocol (FIG. 1a) with a "free text-type" message, and other user devices employing other digital message protocols. The invention is adapted to exploit the free text message capability of the first protocol. In accordance with the invention, the incoming user data messages are packed into one or more free text messages of the first message protocol, and conversely "unpack" free text messages from the data terminal employing the first protocol are unpacked and formatted into the message protocol format employed by the user device 65. The invention eliminates the necessity for expensive translation devices which translate the data, and allows a plurality of user data terminals to communicate via a link comprising the data terminals employing the first message protocol.
