There is a nice Zephyr project (OpenSource RTOS, POSIX compatible) exactly for microcontrollers. While I can agree on making Linux stuff less fatty, I can't agree on doing this way. We have for now two subsystems to serve for serial devices, you are proposing third one for only narrow class of devices. >From my point of view is better to achive your goal with existing system (as a proof of concept maybe even with ugly #ifdef:fery). -- With Best Regards, Andy Shevchenko
