Specify the size of the input buffer in bytes
Description
You configure InputBufferSize
as the total number of bytes that can be stored in the input buffer during a read operation.
A read operation is terminated if the amount of data stored in the input buffer equals the InputBufferSize
value. You can read text data with the fgetl
, fgets
, or fscanf
functions. You can read binary data with the fread
function.
You can configure InputBufferSize
only when the serial port object is disconnected from the device. You disconnect an object with the fclose
function. A disconnected object has a Status
property value of closed
.
If you configure InputBufferSize
while there is data in the input buffer, then that data is flushed.
