how to send extra commands

[W. de Hoog]

Hi,

When reading phonebook data I noticed my phone (samsung m150) responds 
with different indices when I first send AT+INFO before querying using 
AT+CPBR.

Trial and error showed I need to delete items using those indices and 
not the normal ones.

My question is how can I implement to send AT+INFO before the 
ReadPhonebook functions are called?

regards,
