delete (serial) - Remove serial port object from memory
Syntax
delete(obj)
Description
delete(obj) removes obj from
memory, where obj is a serial port object or an
array of serial port objects.
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.
help serial/delete
Example
This example creates the serial port object s on
a Windows platform, 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.
s = serial('COM1');
fopen(s)
fprintf(s,'*IDN?')
idn = fscanf(s);
fclose(s)
delete(s)
clear s
