i created a symbolic link with the below command (on UBUNTU 16.04 LTS 64 bit)
ln -s ttyACM0 ttyS5
to use with a usb pin pad ,but every time i restart the machine the link is broken.
i have little knowledge on linux.After the reboot this command shows that he link already exist.
ln -s ttyACM0 ttyS5 so i have to remove and create again but machine keeps losing the settings.

You probably need to Create a symlink in /dev using /etc/udev/rules

If you do a df -h in a terminal you will see that /dev is "mounted on" udev, not /dev/sdx or anything else indicating a physical disk. udev is a virtual file-system (in memory) that is regenerated every time the system is booted.
That's why your symbolic link disappears on reboot.
