May be you can help. Every time I use the cu command to call a remoute machine, my server try to connect the remoutesystem for a second time if the first call is not in order. My string in /usr/lib/uucp/Systems looks like as following:

ND000040 Any;2 ACU mM9600 004902315414284 in:--in: nuucp word: uulaser

I do not want the second call. It is possible to do only one call ????
