Instrument Control Toolbox    
BytesAvailableFcnCount

Specify the number of bytes that must be available in the input buffer to generate a bytes-available event

Description

You configure BytesAvailableFcnCount to the number of bytes that must be available in the input buffer before a bytes-available event is generated.

Use the BytesAvailableFcnMode property to specify whether the bytes-available event occurs after a certain number of bytes are available or after a terminator is read.

The bytes-available event executes the M-file callback function specified for the BytesAvailableFcn property.

You can configure BytesAvailableFcnCount only when the object is disconnected from the instrument. You disconnect an object with the fclose function. A disconnected object has a Status property value of closed.
