Description

A while back Dan suggested this performance improvement for Network Server.

Instead of calling the getXXX setXXX methods in Network Server,
we can implement either a getDRDARow/setDRDARow or
getDRDAValue/setDRDAvalue methods to bypass the conversion and
minimize object creation. Perhaps the signature would be
something like.

public void getDRDARow(int[] drdaTypes, byte[], startOffset)
