Indicate the total number of values written to the device
Description
ValuesSent
indicates the total number of values written to the device. The value is updated after each successful write operation, and is set to 0
after the fopen
function is issued. If you are writing the terminator, then ValuesSent
reflects this value.
If you are writing data asynchronously, use the BytesToOutput
property to return the number of bytes currently in the output buffer.
When performing a write operation, the transmitted 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 *IDN?
command using the fprintf
function, then ValuesSent
is 6
because the default data format is %s\n
, and the terminator was written.
