NI 6035 board AI trigger problem from Steven Hartmann on 2007-01-29 (gmane.linux.comedi)

I'm attempting to do streaming analog input on an NI 6035 board starting 
on a DIO transition.  So basically, I set start_src to TRIG_EXT and set 
start_arg to 3 (for DIO channel 3).  The trigger signal connected to the 
dio line is normally high and pulsed low.
 
 The problem I am having is it seems the acquisition starts as soon as 
the comedi_command() function is executed i.e. it doesn't wait for the 
pulse to occur.  So does anyone know of a bug or limitation that could 
be causing this problem?
 
 Thanks!
 
 Steve
