I found the main problem - file permissions.
Everything would be easier if the app says "permission denied" instead
of "no valid port".
Making /dev/cuaU0 or /dev/ttyU0 writable is not enough. The problem is
in lock directory:
> ls -ld /var/spool/lock/
drwxrwxr-x 2 uucp dialer 3 Dec 21 13:48 /var/spool/lock/
Must be writable by user running BT747
Even if I am in group "dialer" I cannot connect to cuaU or ttyU. I must
made them writable by everyone.
I will try to find this last problem later.
Thank you for your time!
