problem with blueserial.sh with Nokia 6600

[lluis]

Hello,

i'm trying to access to a Nokia 6600 phone from a
Nokia 770.
With root shell(sudo gainroot), I've executed
blueserial.sh and the result is:

cu: create /usr/spool/uucp/TMP0000000592 - permission
denied
cu: /dev/rfcomm0: line in use

It seems a problem of permissions of cu. Cu is setuid uucp.

I have tried:

chown uucp:uucp /usr/bin/cu
chmod ug+s /usr/bin/cu

and

chown uucp:uucp /usr/spool/uucp/

but the problem is the same.

any solution to this problem?

thanks in advance
