Functions for communicating with Knauer pumps via RS232.

knauerpumpobjreadmaxflow(serialObject, pumpHeadSize)
function maxFlow = knauerpumpobjreadmaxflow(serialObject, pumpHeadSize)
% KNAUERPUMPOBJREADMAXFLOW returns the maximum flow rate of Knauer pumps
% maxFlow = knauerpumpobjreadmaxflow(serialObject, pumpHeadSize) returns
% the maximum flow rate of Knauer pumps connected to a valid serial object,
% as numbers.  If no pump head size is supplied, it will try and retrieve
% it from either the UserData, or by requesting it from the pump directly,
% but if one is supplied, then will retrieve the maximum flow rate set for
% that pump head size.

% checks the number of arguments
error(nargchk(1, 2, nargin))

% if a pump head size was supplied...
if nargin >= 2
    
    % check the input
    if ~isvalidknauerpumpheadsize(pumpHeadSize)
        
        % complain
        error('Must supply a valid pump head size - 10 or 50 [mL].')
    end

else
    
    % fetch it (attempts to fetch it from the UserData, and if not, the
    % pump itself)
    pumpHeadSize = knauerpumpobjreadpumpheadsizefast(serialObject);
end

% the maximum flow rate is simply the size of the pump head (so far)
maxFlow = pumpHeadSize;
