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.
