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

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.
