Serial INSTR
Description
Notification that at least one data byte has been received. Each data character will not necessarily result in an event notification. In other words, if multiple data bytes arrive at once, you may get only one event. After receiving this event, you should query the serial port for the number of bytes available via the VI_ATTR_ASRL_AVAIL_NUM attribute.
