Hi, I'm unable to get a proper response from my GSM modem300, sometimes it responds with nothing, sometimes it replies half of line of ONE message from full inbox, sometimes it just sends the command (AT+CMGR=1) I just sent, back many times.

I'm using Arduino, directly connecting the Tx and Rx of board to Rx and Tx of arduino, and GND to arduino GND.
CODE:
It might be worth mentioning that, I can send messages properly, and make and receive calls with no problem...
