OK, what do you mean by "raw STANAG 5066 PDUs"?

        http://www.isode.com/whitepapers/stanag-5066.html

says "At the modem level, STANAG 5066 uses packets (DPDUs) of a size appropriate to the modem speed."  Are those the 
raw PDUs?

It also speaks of the "SIS protocol", which appears to be the low-layer protocol used to communicate with the "STANAG 
5066 server", which appears to act as a gateway between applications and the STANAG 5066 radio layer.-
