Is it me or this code doesn't run properly on Linux

Ubuntu 15.04, compiles fine, but will stuck at "Ready: received 0000" before timeout, after scratching my head for an entire night checking Teensy(I'm using a ++2.0, not 2.0) and cable. then I found out that it works on OS X. I got the clue from the default device name and a youtube guy using your code is running on OS X too.

I know nothing about serial programming, so i'm not able to fix this.

I'm trying to port the PC code to Windows, still WIP but at least I can get the 0x7202 ready now, just using CreateFile/WriteFile/ReadFile.

the Windows port is done, the protocol is changed and I stripped multiplayer and 2nd stage loader code away, but normal multiboot still works.
