File Descriptor. I can't help with your actual question, though, .. sorry

Thanks Brandon I talked to Rob last night, and now I only need help on the last code section. read() = ReadFile(), write() = WriteFile().

<< Edit >>: The stuff below bolded is what I don't get:

int openSerial(char *port){
   struct termios tios;

   fd=open(port, O_NOCTTY | O_RDWR | O_NONBLOCK);
   if(fd<0){
     sprintf(lastError, "%s: %s\n", port, strerror(errno));
     return fd;
   }

   tios.c_cflag = BAUDRATE | CS8 | CREAD;
   tios.c_iflag = IGNPAR;
   tios.c_oflag=0;

   tios.c_lflag=0;

   //satisfy read immediately.
   tios.c_cc[VTIME]=0;
   tios.c_cc[VMIN]=0;

   tcflush(fd, TCIFLUSH);
   tcsetattr(fd, TCSANOW, &tios);

   return fd;
}
