Setting non-standard baud rate to Serial Port
Using stty, we can only set standard baud rates such as 9600, 19200, 38400, 57600 and so on using the following command: stty -F /dev/ttyUSB0 115200 stty does not allow us to set non-standard baud rate , for example 7667. stty -F /dev/ttyUSB0 7667 We will get the following error: "stty: invalid argument '7667' We can set a custom baud rate using new style termios2 struct with setting BOTHER flag in c_flag member of termios2 struct. Sample Code for setting custom baud rate #include <stdio.h> #include <fcntl.h> #include <errno.h> #include <asm/termios.h> int main() { int fd, ret; struct termios2 config; fd = open("/dev/ttyUSB0", O_RDWR); if (fd < 0) printf("Failed to open /dev/ttyUSB0 - fd = %d\n", fd); // Set custom buad rate ret = ioctl(fd, T...
