ABSTRACT:
An interface device called an adapter is provided for interconnecting data terminal equipment (DTE) to a communication highway. The adapter includes a plurality of command/status registers coupled through a decoding device to the data bus and control lines of a microprocessor. An Internal Modem Interface (IMI) circuit arrangement monitors the decoding device and command/status registers and depending on the contents of the command/status registers and/or the status of the signals on the interface the IMI enables/disables the receive and transmit logic functions of the adapter. The adapter also includes a circuit arrangement which monitors traffic or signals on the data highway without affecting the electrical characteristics of the traffic.
