Hi,
I need to write data to serial asynch. COM port and to check at any time how many data are still to be sent. RS 232 library function for such purpose is GetOutQLen. What is equivalent VISA function ?
VI_ATTR_ASRL_AVAIL_NUM flag can be used in order to determine the amount of data in the INPUT serial asynch. COM buffer, but what about determining number of bytes in OUTPUT buffer ? Is there any VISA function which query number of bytes in OUTPUT buffer/queue ?
br,
Milan.
