Can I use the RS-232 port instead GPIB for data aquisition

I have a program written to couple scope and PC with GPIB. But my new scope does not have GPIB. Can I use RS-232 port for DAQ.

What interfaces are available for your scope?  Is it the same scope you had before, just with new interfaces?  Are the command sets the same?  There's a lot more to consider here.

It is a new scope.But from the same company

If you used an instrument driver, you would have to replace the function calls with corresponding functions from the driver for the new instrument. If you did not use a driver and just used VISA Writes and Reads, you would have to make sure the commands are the same. For  your own code, you would need to add the serial configuration.

Does the new instrument also have an Ethernet connection ?   If so, then LXI communication via the Ethernet is also possible.   the command set would be the same for either interface, unless stated otherwise by the Manufacturer.
