Functions for communicating with Knauer pumps via RS232.

knauerpumpobjwriteerrorio(serialObject, errorIO)
function knauerpumpobjwriteerrorio(serialObject, errorIO)
% KNAUERPUMPOBJWRITESTARTMODE changes the error I/O mode of Knauer pumps
% knauerpumpobjwriteerrorio(serialObject, errorIO) writes the error I/O
% mode for Knauer pumps, where serialObject is a valid serial object
% generated by knauerpumpobj.  0 is OUT and 1 is IN - but it is not clear
% what this actually does.

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

% checks the start mode is valid or not
if ~isequal(errorIO, 0) && ~isequal(errorIO, 1)
    % complain
    error('Must supply a valid error I/O mode - 0 or 1.')

% writes it
knauerpumpobjcomm(serialObject, 'write', sprintf('ERRIO:%.0f', errorIO));
