I want to get data from the Tektronik TDS 3014 oscillosscope via the RS232 port

I have a Tek scope TDS 3014.
This sope has olnly a parallelport (RS323).
Is it possible to get data from this scope the displayed curves, setting etc.).

Yes, you should be able to communicate to your instrument through your serial port. Commands sent to an instrument consist of character strings that the instrument should interpret and perform the desired action. This is true across the GPIB bus and serial ports. You will have to determine what commands are required by your instrument, and send those from your application. For instance in LabVIEw you could use VISA, Serial, 488.2 or 488 vi's to write and read from the correct interface. If you are interested in using a driver that is already developed, we do have a driver for GPIB listed on our web site:
ni.com>>downloads>>instrumetn drivers...
This would require purchasinga GPIB board, but it may be worth it compared to the time to develop a driver for serial.
Also,
if you are looking to deveolp a driver, we do have information for this on our web site:
ni.com>>resource library>>instrumetn drivers...
Good Luck with your application!

I want to interface the same equipment using Ethernet connection. Any information is appreciated.

You can go to the Instrument Driver Network, search for the 3014 or if you have LabVIEW 8.x, go to Tools>Instrumentation>Find Instrument Driver. There is a LabVIEW 8.x project style driver, a LabVIEW 7.0 and 8.0 plug and play driver, and an IVI driver. All say that they support Ethernet. The instrument driver main page has information on what a driver is and how to use it. You'll also need to have NI-VISA installed and then you will need to configure MAX to detect the instrument.
