The EIA-366 interface defines the Electrical signal characteristics, interface mechanical characteristics, functional descriptions of interchange circuits, and standard interfaces. The EIA-366 interface defines a complete interface between Data Terminal Equipment (DTE) and Automatic Calling Equipment (ACE). The electrical requirements for the drivers and receivers are identical to those in EIA/TIA-232-E [RS232]. The EIA366 interface bus is obsolete, as is the RS232 interface. However; the RS232 is still in wide spread use.
The term "RS" has been obsolete for years now, all RS specifications should be referred to as EIA standards.
