I noticed in the IO primitive manager section in the RTEMS POSIX guide that there are a read and a write function, however the IO guide are not finished yet, so I don't know if those functions are in good shape to use. Are they ok ? Also is there a tcdrain (from termios.h) equivalent function for RTEMS?
I want to make a hardware loop with the board and a pc with linux through serial communication. Is there any RTEMS specific functions to send and receive data through serial UART ? Thanks !
