function resp = readbin(mm,index,timeout)
%READ2BIN Retrieves a block of DSP memory as hexadecimal strings.
%   DN = READ2BIN(MM)
%   DN = READ2BIN(MM,[],TIMEOUT) - reads a 
%
%
%   DN = READ2BIN(MM,INDEX)
%   DN = READ2BIN(MM,INDEX,TIMEOUT) - reads a ?
%
%   HS = READ2BIN(MM) - returns a binary string representation of 
%   the DSP's numeric values.  For arrays, the returned values will 
%   be a cell array of binary strings.  Conversely, if MM.SIZE equals 1,
%   (indicating a scalar), the output is an array of hex characters. 
%
%   DN = READ2BIN(MM,TIMEOUT) - The time alloted to perform the read is 
%   limited  by the MM.TIMEOUT property of the MM object.  However, 
%   this method can be used to explicitly define a different timeout
%   for the read.  For example, this may be necessary for very large 
%   data transfers.
