serial communication

[Tomasz]

I am trying to communicate with my serial port sending data to the external device. I am trying to send some integers. Everything works fine if the integers is of the positive value, but as soon as I try to send the negative value my com port does not send anything out. Have anyone encountered this problem?

Hi Tomas

I am attching your "SubVI" after Modification. You will have to look at it and try it. See the Comments on the Diagram.

Let me Know If it works. I could Not try it at my end due to time and incomplete Main VI.

Good Luck!!
