standardowo ten port jest zajęty, aby użyć go przez aplikacje dstarrepeater trzeba zmienić wpisy w dwóch plikach
/boot/cmdline.txt
/etc/inittab
co pięknie jest opisane np:
http://raspberrypihobbyist.blogspot.com/2012/08/raspberry-pi-serial-port.html
First, disable the boot up and diagnostic output to the serial port.
sudo vi /boot/cmdline.txt
and remove the two options referring to the serial port.
So, this
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait
becomes this
dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait
Second, disable the login prompt
sudo vi /etc/inittab
find the line near the end
T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100
and delete it or comment it out by putting a # at the start of the line.
Reboot and the serial port will now be free for your exclusive use.
