I connected my mobile to the laptop to COM1 serial by the cable came with mobile, then I used the Hyper Terminal. Every thing is okay I can write command and Read the Response (like read SMS) by its configurations using AT-Command. BUT.......... When I built my project on labview the result was wrong, when I write to VISA "COM1" (AT) as example , the response should be (OK) but it read (AT) again so the Read from VISA read just what I wrote in VISA write "it's wrong". I thought about ECHO but it's already works fine on Hyper Terminal, so the problem is not ECHO.
When I Built the project on labview I start with VISA configuration then VISA write then Delay time then VISA read, Finally VISA Close. Am I wrong????
Can any one help me???? please
