What is the proper way to know if a send is successful?

[fabian chatwin cedrati]

I am dealing with a SCP that doesn't return a release response after a Dclient send. I know this is wrong but the image does get to the other side.
Currently to know if the send has success I check into command_results the value of 0000,0900 and 0000,0902.
But from this SCP I get command_results empty. However the image is arrived and the Ruby dicom log recognize it.

Do question is: how to correctly handle the result? A part from protesting with the SCP vendor that doesn't perform the release, is there a better way to know the result of send?

I'm now digging into the link class in search of clues.

Thank you
