write and read with leybold device

Since it doesn't work with hyperterminal, there are few things left to try and it is not a LabVIEW problem. You could try a different serial converter but you need to contact the vendor st this point. All if they have a utility program.

To display on a chart, you just have to parse the string to get the numeric value. To display on a graph, you need to parse and accumulate the values to an array. Examples come with LabVIEW and you should take some of the free tutorials.
