The original ccTalk protocol did not use any kind of encryption. It was thought that the security in a serial interface was so much better than a parallel one that no. The ccTalk protocol is used to transfer information and commands to various money processing device, including coin/bill acceptors and coin. The OSI 7-layer network model is of limited use for a simple control protocol such as cctalk. Whereas the task of writing software for full-blown networking.
