Hi,

I would suggest you to describe in more details which behavior you are obtainning. Without knowledge of which operation you are trying to do, which exactly driver you are using as well as when the error occurs, it is hard to give any suggestion.

the problem is when I use my driver for modbus Ascii, appears and error 1073807339. I think that is error occurs because Labview change the termination CR LF .. because when I use that driver in toher device and I read the buffer with read VISA the termination character is SP LF... so I think because Labview change it.... I hope that somebody have a solution to my problem.. or a mosbus driver ascii.

Thanks
