What device are you trying to communicate with?  Do you have documentation on the communication protocol?

Wild guess: your sensors don't send a line feed as termination character, but that is the default of your VISA Configure Serial Port.

Likely not just that. It may be necessary to append some termination character to the sent command too, before the device will attempt to decode the command.
