 Hi

I want to do continuos aquisition from all AI channels
of NI 6025E (and 6052E).
More precisely I what that board do data aquisition all time and
program (user space of cause) be able to read data at any time.  
I suppose to send comedi_command() with TRIG_NONE as stop condition.
And read() in forever loop.
To do this I slightly modifed demo/select.c
But after about 80KBytes read() return error:
read: Broken pipe
This error appears with both boards.
What I do wrong ?

details: Linux 2.4.26 without any patches, comedi-0.7.68, comedilib-0.7.21 

Thanks

 Andrey
