writelock [on|off|auto]
In addition to access control lists, not all users may be able to write to
the same window at once. Per default, writelock is in 'auto' mode and
grants exclusive input permission to the user who is the first to switch
to the particular window. When that user leaves the window, other users
may obtain the writelock (automatically). The writelock of the current
window is disabled by the command “writelock off
”. If the user issues
the command “writelock on
”, he keeps the exclusive write permission
while switching to other windows.
