comedi_command acquisition mode

Hi all,
I have a problem with the comedi_command function.
I Have seen the cmd program that is in the demo directory of comedilib, and I
have found that if I set the cmd->stop_src = TRIG_NONE the acquisition run
continuosly until I use comedi_cancel command.
SO I have tried but with this option the results of the acquisition are
absolutely errors. To verify that I have tried with a normal acquisition (not
continuos) and all work ok.
Is it a problem of continuos acquisition by comedi_command ?
There are flags that I forget to set ? 
There is someone who have used this comedi_command procedure ?
Thanks a lot for every help.
Fabio
