Keithley 213 Quad Voltage Source - GPIB

I've removed a Keithley 213 Quad Voltage Source from the shelf with a thought that perhaps it might be made useful at last. It sat on the shelf because I could never talk to it over the GPIB and that's the only way to enable outputs.
Anyone here have experience with this?
I can't afford the National Instruments software, which seems to be the only option...

NI offer Labview for makers for 50$. It is the 2014 version and works really well.
I also got the original Agilent 82357B for about 90$ (local electronics junkyard).
And got the raspberry pi for metrology project (see on the metrology forum). I use it control and log a DMM and power supply using Python scripts.
Turns out RPi comes with a free version of Mathematica so I am now trying to see if I can connect the two.

Assafl: Thank you very much.
I did a bit more research and found the NI Drivers (I have the NI USB interface) and a GPIB toolkit by KE5FX. In the toolkit is a command line tool called query. The Keithley is at address 9 and I see it on the buss when using another tool.
When I send the 213 a command, I consistently get back a reply that looks like it's trying to send me some data.
A1C0P1R0V+00.00000
The error LED on the 213 is lit after sending any command. If I ask what the error is using E? I get the same:
C:\Program Files (x86)\KE5FX\GPIB>query.exe 9 E?
A1C0P1R0V+00.00000
Any clue what this is?

Never mind
I got it.
Had to power-cycle the Keithley 213.
Also, am now using EZGPIB, which provides a simple programming interface. Quite powerful.

A1C0P1R0V+00.00000 is a status output. It's listed deep within the Keithley 213 manual.

PM me if you need help. I have a 213 and have done a lot of GPIB with it with Visual Basic. I started to write an entire app for controlling it, got part way, but I know the device inside and out.

Thanks very much!
Maybe we can port your VB stuff to C.
