It has 16 bit full duplex hardware (like the MSS system has) but it is ESS's own implementation and is not MSS compatible. However, there is an ESS driver submitted by someone else included in Luigi's tar file on his homepage. If that supports full duplex, it would be worth modifying Luigi's driver to support ESS.
