When used in reference to sound cards and Internet phones such as WebPhone and IPhone this means the ability to send and receive audio at the same time like a standard telephone. Some sound cards and systems require a special full duplex audio driver which is software usually available from either the manufacturer of the sound card or the program itself.
If you are searching for duplex drivers for your system, then try using Alta Vista with a search string of: full duplex {name of software} {type of hardware}.
