Switch com port in Arduino 1.6.2

Just downloaded Arduino 1.6.2. I need to switch from comm 1 to comm 4 in the software. How do I do that?

I set everything up and the board lights up. The device driver found the board on usb 4. How do I change from com 1 to com 4 in the software? It is trying to use com 1.

New to arduino.

i didnt understand question here. When device manager detect port as com 4 while u think it will change to com4.

In software whichever port detected automatically assigned. else goto to tools->Serialport chose port being detected.

I need to switch from comm 1 to comm 4 in the software. How do I do that?

which comport using in device manager??? if it com1 & u wanna change to com4

just goto device manger-> port-> right click-> properties-> advance properties in port-> choose port you needed

Thanks. Got it. Works now.

Thnx
