Hi, I'm currently contriving a network driver using the serial port. I've created my own line discipline (and tests prove it reads well), but I can't write to the port : I tried to use tty->driver.write(tty, 0, msg, strlen(msg)) (the same way that in printk.c, i.e. after testing that tty->driver.write exists) but it crashs into a segmentation fault. Since the driver implementation is not mine (I'm just using the serial module), I can't check the function's address, but I'm sure that the tty is good and so is the msg. Does anyone know in which way I can search a solution solution ? Thanks, -- Laurent Hugé. -- Kernelnewbies: Help each other learn about the Linux kernel.
