cprsave calls cprsave(). Syntax:
{ 'enum': 'CprMode', 'data': [ 'reboot', 'restart' ] }
{ 'command': 'cprsave', 'data': { 'file': 'str', 'mode': 'CprMode' } }
cprload calls cprload(). Syntax:
{ 'command': 'cprload', 'data': { 'file': 'str' } }
cprinfo returns a list of supported modes. Syntax:
{ 'struct': 'CprInfo', 'data': { 'modes': [ 'CprMode' ] } }
{ 'command': 'cprinfo', 'returns': 'CprInfo' }
