Is SQL*Plus Resumable?

I am using resumable space for a lot of my operations. However, it seems as though the SQL*Plus copy command doesn't respect the resumable feature?

Note, I am issuing an "alter session enable resumable timeout 14400" through a login trigger. I know this works because if I do the same type of operation through an INSERT/SELECT through a dblink, my session waits for more space to be added.

user@whouse1.us> select sysdate from dual;

Is RESUMABLE space not available with SQL*Plus copy?
