I don't have a solution for you. Actually we're just beginning to look into writing our own dh+ driver. Would we be able to look at a copy of your source code? You can email it to [email protected]

Thak you

You should give Quest Technical Solutions a call (519.699.5886). We are a company that is made up of ex-SST (S-S Technologies) designers. I.E. We designed the SST DH+ network interface card, SST ControlNet cards, SST Profibus cards, etc. etc. We also do a lot of work with the ControlLogix platform (backplane modules for industrial networks). Ask for Lorne Diebel...
he will give you a fair price for consulting, if that is what you need in the end...

best regards,
