Also, from you screenshot it looks like you have another SMS application open. If this is using the serial port you will have to close it. Only one application can open the serial port.

Also, are you sure COM18 is correct? Sounds like a high number.

Don't panic! Did you use the Simple Error Handler vi or the Explain error menu function to get the error description?

It says that VISA cannot access the resource; in other words, COM18 is currently open by another program (or driver).

Try to guess which one could be accessing it and how to close it.

Also, use the simple Wait(ms) function instead of the Wait until next... This last function doesn't work the way you believe.

Is it possible that the cause of this error is by my Itegno application? Because my project is to send an sms with my Itegno gsm modem with the aid of labview

Well then just try and quit this Itegno application, then run your VI again. If you have it running it might reserve the serial port which causes your VI not to be able to open the port.

Firstly, thanks for replying. I've tried to off the application. It works, but i couldnt receive any SMS from it even though there wasnt any error
