My application requires changing the state of the output lines.  I am using the function Dig_Out_Line to change the status of the 16 lines from low to high and so.  It works fine without any problem.  What I want to do when I run the program, I want the user to turn the trigger on so the lines can start changing.  I can�t find any function to control the trigger.  It seems like the only function that controls the trigger is the Dig_Trig_Config.  I can�t use this function, because it is not suitable for what I am doing.  I am not sending a pattern to the output; however I am creating a pattern by changing the state of the lines by using Dig_Out_Line.  I want to know if there is another function I can use besides the Dig_Trig_Config.  I want to know how I 
can solve this problem without using the Dig_Trig_Config function.  I wonder if there is a function that gives direct access to the ACK line.  For example, I can check the status of the ACK line and start changing the status of the lines when ACK is high.  
I appreciate your help.
