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
.
