### Serial Command Syntax

< > = Required argument. Replace appropriately.

For example:

-u <DB_User_name> becomes -u av where av replaces DB_User_name.

| = Mutually exclusive arguments. Choose one from the list.

{ } = Used with | to specify a list of choices for an argument.

[ ] = Optional parameter.

Precautions for Correct Use: Unless otherwise stated, commands will respond with !OK on success and !ERROR on failure.
