Device Modem

A modem (modulator-demodulator) is a device that modulates an analogue carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The philosophy is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data.

Generally this device has been superseded by other communication technologies and is only required for historic purposes.

Only one system modem is currently supported.
