It turned out that it was a problem with the terminator. It was working with the bdc-comm utility, but was taking too long to return a signal to operate with the crio. After replacement we got it to work.

In response to the previous post it was a typo on the post, not the code. Otherwise we would not have been able to tell you what it was returning or been able to compile the code.

Thanks for the responses.
