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.

G G1,10~ The command “G” is used to query or

modify a router configuration parameter or

parameters.

“R”: Router Reset

Use this command to force the routing switcher to reset, by sending it the command

"RESET". If an administrator password has been set (using the “G ADMIN_PASSWORD”

command described later in this document), then the password must be sent in a “K”

message prior to sending this command, else this command will generate an error. For

example, the command:

**RESET!!

would initiate a reset (if the password has been entered, if required), and when the router

finished the reset operation, something like this would be received, just as if the router

had powered up:
