hi,
I must thank the forum for helpful suggestions posted. now the module has worked somewhat good, now by sending command AT i could see OK printed on the lcd screen. now to read the first msg using AT+CMGR=1; i receive data along with delivery OK and info s of the CMGR pattern, and my DOUBT is
1. how to disable the delivery message and
2. how to print only <data> out of RCREG format.
+CMGR:<stat>,<oa>,[<alpha>],<scts>[,<tooa>,<fo>,<pid>,<dcs>,<sca>,
<tosca>,<length>]<CR><LF><data>
