% Change History
%      1999-01-05 (DaB)  Created
%      1999-01-07 (DaB)  Fixed bug in indexing
%      1999-02-04 (DaB)  Changed input format
%      1999-02-04 (DaB)  Changed name to setDM
%      1999-02-05 (ToNo) Changed name back to getDM
%      2000-03-31 (UvAn) Changed gui.modems to modems
%      2000-10-23 (GS)   Modified for different lengths of service names
%      2001-06-15 (Bosse) Octave port initiated
%      2002-07-01 (PeKa) Octave to Matlab compatibility port
%      2002-10-16 (ToNo) Cleaning up the code
%      2003-11-03 (ToNo) Lists now use cell arrays for both Octave and Matlab
%      2003-11-03 (ToNo) Fixed comparisons even if modemlist contains
%                        trailing spaces
%      2008-08-25 (ToNo) Changed the trailing space fix to use strtrim,
%                        and made comparison exact (diff btw VDSL and VDSL2)
