ABSTRACT:
A self-configuring startup procedure for communications devices, including telecommunications adapters, provides unambiguous identification of the telecommunications adapter, or other communications device, connected to a serial port. The procedure does not interfere with the operation of other existing I/O devices that might be connected to the serial port, such as network, MIDI, or other serial I/O devices. The I/O device is connected to a computer through a serial interface and a serial link. When the I/O device exits a reset state, the I/O device sends across the serial link to the computer a "beacon" signal identifying the I/O device. In particular, during the beacon phase, the I/O device communicates identification and configuration parameters. Preferably, the beacon phase may be instigated by the computer using the same serial-link communications channel.
