yes, there is a null byte in the first column.

the permission denied is because ivtscd is running as standard user
(for now), that'll not be a problem later.

as the PC is connected to it via RS232. as soon as I unplug the RS232
cable, figures go down to about -0.7A as it is supposed to be ...

this means that there must be something wrong with the SCD and I need
to figure out what ...
