DMCA Declares Serial Cables Illegal?. I’ve recently had an interesting run-in with the DMCA… apparently, US Customs has rejected entry of a PC<->Sega Dreamcast serial cable into the US, supposedly due to copyright violations. This cable was to be used for Dreamcast programming for the Real-Time Systems class offered at my university. This seems to be a clear case of the DMCA abridging a perfectly valid educational use of a perfectly legal piece of hardware. I’ll be keeping the most recent version of my story here; otherwise see below for what I currently know. [kuro5hin.org]
