I have looked at the RS485 linef with an oscilloscope, but I haven't had the chance to use a digital oscilloscope so the signal is just there for one second and gone the next. The moment the signal is there does correlate with when I'm sending the signal, so I am left to asume that the right signal is being send.
As for the sniffers, thank you for the recommendations, I'll have to look into them.
I have also switched off of auto-direction in the past few days. It's generally better to have more control over things like that.
