Remove a serial port object from memory
Syntax
Arguments
obj |
A serial port object or an array of serial port objects. |
Description
delete(obj)
removes obj
from memory.
Remarks
When you delete obj
, it becomes an invalid object. Because you cannot connect an invalid serial port object to the device, you should remove it from the workspace with the clear
command. If multiple references to obj
exist in the workspace, then deleting one reference invalidates the remaining references.
If obj
is connected to the device, it has a Status
property value of open
. If you issue delete
while obj
is connected, then the connection is automatically broken. You can also disconnect obj
from the device with the fclose
function.
If you use the help
command to display help for delete
, 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, disconnects s
from the device, removes s
from memory using delete
, and then removes s
from the workspace using clear
.
