title: Samsung Galaxy S and Hyperterminal
body: <p>When connecting Samsung Galaxy S via USB to hyperterminal, I cannot retrieve any messages or send messages. The commands "AT", "AT+CMGF=1" work, and "AT+CMPI=?" return different memories available. But when I try to execute the following command: AT+CMPI="SM" (or any other memory) I get an error. In addition when I try AT+CMGS="..." it gives an error too. What can it be?</p>
  
  <p>Thank you!</p>
