The READ command returns all the parameter values of the defined setting
environments. The setting environments are displayed by means of linefeed.
The TEST command returns all supported values. In the response, they are displayed
one by one by using “PDP_type” values supported by MS as index. Each entry takes
a determined PDP_type value, and includes the supported value ranges of other
parameters under the value of PDP_type. The entries are displayed by means of
linefeed.
