connecting RS 232 serial port to USB

[dp10ME90R04]

how to connect RS 232 to usb in labview. can any one give example for this. i have collected data using read and write visa by selecting COM3 port. it is showing that the data is interrupting. i am using labview 8.2 version for collecting data.

usb is just the same as non-usb, or your usb to serial controller is one of the few that don't act well.

With good hardware it should function as a built in port.

But maybe com3 is your infrared port, and not your usb controller. did you check in the device manager?

i have checked in device manager. COM3 is a usb to serial port converter. how to control data. can you draw a block diagram and send me.
