In configuration mode（M0=1, M1=1, M2=0），
User gives the module instruction (HEX format): C1 C1 C1,
Module returns the present configuration parameters.
For example, C0 00 00 18 4E 1C.
In configuration mode（M0=1, M1=1, M2=0）,
User gives the module instruction (HEX format): C3 C3 C3,
Module returns its present version number, for example C3 0071 XX1 XX2 XX3 XX4 XX5.
70 here means the module model (E70 series); xx1 is the version number and XX2 XX3 XX4 XX5
refers to the other module features.
