I just try to develope an application that send and reveice SMS throught the COM Port that is connected to a nokia phone ! (ok nothing speacial I thought)
I just connect to my nokia 6600 by hyperterm over Irda. When I enter AT i've got the answer OK. Unfortunatly no other AT command (like the needed AT+CNMI) workes. I always got back ERROR from the phone. It looks like only simple AT Commands (like ATD or ATI workes !).
So what is my fault ? Can you please help !
