i am trying to figure out how to record when a reset happen in the machine. i konw there is something to do with the stauts word and Bit 3 is the one dedicated to reporting resets. but i do not know how to make it works does anyone have a labview program can check the status word of bit 3.

Serial polling the device will returnt he status byte of the instrument. From LabVIEW, there is a Serial Poll vi that will return this byte which you will need to interprete bitwise according to your instrument's documentation. From other environments, you can use the IBRSP function. Documentation on the supported 488 functions can be found in the Software and User manuals:

It sounds like you want to know about doing serial polling in LabVIEW. Here's a document that should help:
