In , Gottfried Ungerboeck from IBM Zurich Research Laboratory applied channel coding techniques to search for new ways to increase the speed of modems. In other projects Wikimedia Commons. A single additional channel in the reverse direction allowed the two modems to communicate how much data was waiting at either end of the link, and the modems could change direction on the fly. Speeds are usually on the order of or gigabits per second. The now-standard Hayes command set included instructions for picking up and hanging up the phone, dialing numbers, and answering calls, among others.
