Indicate the total number of values read from the device
Description
ValuesReceived
indicates the total number of values read from the device. The value is updated after each successful read operation, and is set to 0
after the fopen
function is issued. If the terminator is read from the device, then this value is reflected by ValuesReceived
.
If you are reading data asynchronously, use the BytesAvailable
property to return the number of bytes currently available in the input buffer.
When performing a read operation, the received data is represented by values rather than bytes. A value consists of one or more bytes. For example, one uint32
value consists of four bytes. Refer to Bytes Versus Values for more information about bytes and values.

Values
Example
Suppose you create a serial port object associated with the serial port COM1.
If you write the RS232?
command, and then read back the response using fscanf
, ValuesReceived
is 17
because the instrument is configured to send the LF
terminator.
