BytesAvailableFcnMode

Specify if the bytes-available event is generated after a specified number of bytes is available in the input buffer, or after a terminator is read

Description

You can configure BytesAvailableFcnMode to be terminator or byte. If BytesAvailableFcnMode is terminator, a bytes-available event occurs when the terminator specified by the Terminator property is reached. If BytesAvailableFcnMode is byte, a bytes-available event occurs when the number of bytes specified by the BytesAvailableFcnCount property is available.

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

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