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 M-file 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.
