00037 /* Klaas Gadeyne, Mon August 11 2003
00038    - Added "channel" param to lowest(), highest(), resolution() calls (these
00039    are mostly configurable on a per channel basis.  If not, there's
00040    no problem
00041    - In comedi, this is also done for their "binary"-counterpoles.  I
00042    don't know if this is necessary
00043 
00044    Klaas Gadeyne, Wed August 20 2003
00045    - Added rangeSet() and arefSet() methods, that allready existed in
00046    the comedi implementations of these interfaces
