Novell Semahpores work by finding a TSR in memory and attaching the
semaphore to it. Normally it attaches to the first TSR, but if
SemAttachTo is set it will attach to a specific TSR. If SemAttachTo is
empty it will be set to the name of the TSR that MarxMenu uses to attach
the Semaphore. That way you can read it's value.
SemAttachTo = 'LSL'
