InputBufferSize

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, fget, 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, that data is flushed.
