&SHLP.PORT #port=+port controls access to destinations by the TportLock on Rooms. The default TportLock on Rooms in this codesuite is to check the TportLock on the Upzones in sequence and, if any allow it, the lock passes. This means it's most effective to control access to root @regions while sub-regions offer finer control.
