Help to use MDM2

I’m using GM862-GPS.I read that we can use MDM2 also.I have tried several times to use MDM2,but failed.

Following is one of the example I tried out:

import MOD
import MDM
import MDM2
res = MDM2.send(‘AT#MONI\r’,0)
gsm_res = MDM2.receive(10)
print gsm_res

It gives following error:

AttributeError: send

If I use MDM instead of MDM2 then it works fine.Can anyone give any example using MDM2?
