Disconnect a serial port object from the device
Syntax
Arguments
obj |
A serial port object or an array of serial port objects. |
Description
disconnects fclose(obj)
obj
from the device.
Remarks
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.
If you use the help
command to display help for fclose
, then you need to supply the pathname shown below.
Example
This example creates the serial port object s
, connects s
to the device, writes and reads text data, and then disconnects s
from the device using fclose
.
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.
Functions
clear
, delete
, fopen
, stopasync
Properties
disp (serial) | fgetl (serial) |
