communications software to the DATA/COMMAND connector on the back panel and configure the data channel for the type of data that is going to be transferred. For example, if an asynchronous device is going to be connected to the data channel, you must set the speed of the channel, the word length, the number of stop bits, whether or not you are going to have parity checking, the flow control type, and other aspects of asynchronous data. After you have configured the data channel, remove the command port device and connect the data channel device, allowing data to be transferred from the asynchronous device to the MultiMux’s input/ output circuitry

De facto standards A de facto standard is one of two types of voluntary standards recognized by a given market. It is introduced by a single vendor and becomes a standard by its widespread use and acceptance by other vendors. AT&Ts Bell 212A, IBMs Binary Synchronous Protocol or DECs VT-100 terminal protocol are examples of de facto standards. Compare with de jure standards
