Hi all! I have a question about work with serial port (rs232) in kernel How todo this? Here http://www.kernelnewbies.org/documents/kdoc/kernel-api/linuxkernelapi.html iam not find any docs about serial rs232 communication. For example i have in user-space this OpenPort() implementation for my programm: ------------------------------------------ #include <sys/ioctl.h> #include <linux/serial.h> #include <unistd.h> #include <termios.h> ... ... sprintf(devName, "/dev/ttyS%d", ComNum - 1); hComm = open(devName, O_RDWR | O_NOCTTY | O_NONBLOCK); if(hComm < 0) return false; BaudRate = B9600; fcntl(hComm, F_SETFL, 0); termios dcbComm; tcgetattr(hComm, &dcbComm); cfsetospeed(&dcbComm, BaudRate); cfsetispeed(&dcbComm, BaudRate); dcbComm.c_cflag &= ~(PARENB/*|CSTOPB*/|CRTSCTS|CSIZE); dcbComm.c_cflag |= CREAD|CS8; dcbComm.c_cc[VMIN] = 0; dcbComm.c_cc[VTIME] = 10; dcbComm.c_iflag &= ~(INLCR|IGNCR|ICRNL|IUCLC); cfmakeraw(&dcbComm); /* termios_p->c_iflag &= ~(IGNBRK|BRKINT|PARMRK|ISTRIP|INLCR|IGNCR|ICRNL|IXON); termios_p->c_oflag &= ~OPOST; termios_p->c_lflag &= ~(ECHO|ECHONL|ICANON|ISIG|IEXTEN); termios_p->c_cflag &= ~(CSIZE|PARENB); termios_p->c_cflag |= CS8; */ tcflush(hComm, TCIFLUSH); tcsetattr(hComm, TCSANOW, &dcbComm); ------------------------------------------------ How todo this in kernel mode? Btw. I write kernel module for device connected through rs232... DaemonSerj ----------------------- mailto:DaemonSerj@mail.ru -- Kernelnewbies: Help each other learn about the Linux kernel.
