fclose (serial)
(To be removed) Disconnect serial port object from device
This serial object function will be removed in a future release. Use
serialport
object functions instead. For more information on updating your code, see Version History.
Syntax
fclose(obj)
Description
fclose(obj) disconnects
obj from the device, where obj is a serial
port object or an array of serial port objects.
Examples
This example creates the serial port object s on a Windows® platform, connects s to the device, writes and reads
text data, and then disconnects s from the device using
fclose.
s = serial('COM1'); fopen(s) fprintf(s, '*IDN?') idn = fscanf(s); fclose(s)
At this point, the device is available to be connected to a serial port object. If you
no longer need s, you should remove from memory with the
delete function, and remove it from the workspace with the
clear command.
Tips
If obj was successfully disconnected, then the
Status property is configured to closed and
the RecordStatus property is configured to off.
You can reconnect obj to the device using the
fopen function.
An error is returned if you issue fclose while data is being
written asynchronously. In this case, you should abort the write operation with the
stopasync function, or wait for the write operation to
complete.
