Servermode on Sinumerik T3

[malter]

Hi, i'm quite new to the software dnc precision.

I try to load programs and tool corrections from a Sinumerik T3 in Servermode.
As far as I can tell the files are read perfectly well but after that there is a "filename error" and the downloaded programs won't be saved.

The thing is, I need to read programs with multiple end marks. There are two channels that are read one after another in the same run.
So after the first end mark I have to keep on reading.
How could I solve those issues?
