Receiving SMS

[paem]

I have a GSM modem and can sent messages. But I can't sent a message into it. When I tried the first time, there were things inside the read buffer. And now there's nothing. Please look into it. Thank you.

Not sure if this is the problem, but you are sending your Write Return count (number of written bytes) into your Receive bytes.

Also, the sequence structures are unnecessary and hiding some wiring problems. Do a diagram cleaup (Ctrl+U) and start removing them (right click, remove sequence) .

The sequence structures might also be confusing when your wait actually happens. I would suggest moving your wait to between two VI's like this.
