i use a iup.timer interrupt to read new values every second and try to
display them:
local s = comPort:read(64, 600);
if s ~= "" then
messages.append = s;
plot:Add(plotX, tonumber(s:match("%d+")));
plotX = plotX + 1;
plot.redraw = "CURRENT";
end;
As i figured out meanwhile the "plot:Add(..)" statement crashes silently.
The next statement "plotX = plotX + 1;" does not become executed, hence
the plot.redraw statement will not be executed too.
