Leader and Trailer

The simplest possible command string would be “**!!” which consists of the leader and
trailer characters but no command between them. This command string would generate
the response “**OK!!” followed by “CR”. This can be useful for verifying that the serial link
to the switcher is operational.

The following is the set of commands available for sending to the router, a subset of
which may be implemented in any given routing switcher.
