[Linux-gpib-general] computer in listen-only mode?

[Hernán F. <hj...@hj...>]

Is it possible to run a device (a ni_pci in particular) in "listen only"
mode? Instead of being a controller, I'd like it to be a listen only
device, so I can emulate a plotter

My idea is to just grab all of the HPGL commands a device sends and then
convert into PDF.

This has already been discussed 2 decades ago:
https://sourceforge.net/p/linux-gpib/mailman/linux-gpib-general/thread/446940000.1056300621%40%5B192.168.1.1%5D/#msg2697429
but the solution is specific to a particular device.

The NI  forums mention:

#define IbcLON 0x0022 /*Enter listen only mode*/

but it doesn't seem like linux-gpib implements this?

Thanks
