Note: The <name> parameter '2' can only be used, in combination with valid <speed>
and <ce> parameters.
Certain combinations with <name>= 2 are not allowed. For example, if the settings
were at+cbst=0,0,1 and you set after this at+cbst=0,2,1 . The ME will return "Error"
because the setting at+cbst=0,2,1 is not allowed.
The parameter shall be used in an appropriate context. i.e. at+cbst=66,2,1, is
accepted.
