Yes, indeed. > If it is so, I will wait for another solution ;) I'm not sure waiting will help. The roasted pigeons will not come flying into your mouth. The possible solutions have been sketched out for you: a) open the device file from the kernel (described by Jan): actively discouraged by the kernelnewbies.org FAQ document, and probably won't even work IMHO b) program the serial port directly (described by Jan): will work only with one type of hardware and you'll have to disable the regular serial driver first; frowned upon by kernel gurus as "reinventing the wheel" c) abuse the line discipline interface (described by me): moderately well documented, and there's precedent for using it that way in the well-accepted PPP module as well as my humble contribution, the ser_gigaset driver; requires a userspace daemon for pushing the line discipline module on the serial port and keeping it there d) use the serio interface (described by Ying Huang): potentially cleaner conceptually and seems to work without a userspace daemon, but apparently not documented anywhere except in the source files drivers/input/serio/serport.c and linux/drivers/input/mouse/sermouse.c Now it's your turn to decide.
