Hello, Is there any way to access the serial port from within kernel code? I came across this code, while googling, which is supposedly dangerous. > struct file *filp; > mm_segment_t old_fs; > filp = filp_open(name,flags,mode); > old_fs= getfs(); > set_fs(KERNEL_DS); > filp->f_op->read(filp,buffer,count,&filp->f_pos); (from: http://mail.nl.linux.org/kernelnewbies/2001-02/msg00068.html) Morever, I don't have a filesystem in the kernel, and so I guess, this won't work. Is there any other way? One way, I could think of, is to make the static functions used ``internally'' by the driver, public (non-static) and using those functions directly; but I am not sure if this is the best way out. chyrag. -- Chirag Kantharia, symonds.net/~chyrag/ -- Kernelnewbies: Help each other learn about the Linux kernel.
