-------Yes, you are right. "^NDISSTATQRY" command isn't implemented on all modems.
-------But it is sure that "^NDISSTATQRY" command will be implemented on the modems with standard ECM port.
-------And the NDISDUP solution is only implemented for the modems with standard ECM port. (It is marked with 
the rules file)
-------For other modems without standard ECM port, such E367/ E392/E1820/E3276, etc. 
-------They can support QMI or NDISDUP command dial-up through the endpoint 0 of its net port, but not 
through pcui port.
-------So these modems are not the targets of this NDISDUP solution(through pcui port).

----- For other modems without standard ECM port, such E367/ E392/E1820/E3276, etc.
-----It is better to dial-up with ppp modem.
