I've solved my problem by adding this udev rule:
KERNEL=="ttyUSB*", ATTRS{idVendor}=="1d6b", ATTRS{idProduct}=="0002",
SYMLINK="modem", OWNER="smsd", GROUP="dialout", MODE="0660"
Now I have:
# ls -l /dev/modem
lrwxrwxrwx. 1 root root 7 26.7. 16:56 /dev/modem -> ttyUSB3
# ls -l /dev/ttyUSB*
crw-rw----. 1 smsd dialout 188, 0 26.7. 16:56 /dev/ttyUSB0
crw-rw----. 1 smsd dialout 188, 1 26.7. 16:56 /dev/ttyUSB1
crw-rw----. 1 smsd dialout 188, 3 26.7. 16:56 /dev/ttyUSB3
In this configuration it works for my needs. But now I encouraged
another problem. The device unsuspectingly disconnects and then
reconnects by itself. The /dev/modem symlink disappears after this.

How can I find what causes these disconnections?
