16-Port asynchronous adapters
The family of adapters is based on a common functional design. The individual adapter characteristics, however, are determined by the supported device interfaces. The family consists of two adapters, the 16-Port EIA 422A asynchronous adapter and the 16-Port EIA 232 asynchronous adapter.
Note: The following section is not applicable to the Itanium-based
platform.
The family of 16-port adapters is based on the dual universal asynchronous receiver and transmitter (DUART) chip, which provides two serial communications channels. More information on the DUART chip and its functionality can be found in the 16-Port Asynchronous Adapter Hardware Information.
