GPS Data Logger Software - BT747

I had some problems, to connect the Holux M1000C to my Apple. First there was no serial port in the Dorpdown Menu wich succeded. After reading the ports there occured the usb-port "/dev/cu.Holux_1000C_SPPslave_1". I tried again but the system wasn't able to connect because of any "portinuse"-trouble.
Once again Mario De Weerd gave me the hint. Under: http://bt747.wiki.sourceforge.net/mac_installation, there is a special mac installation describend and the terminal commands "sudo chmod 777 /var/lock" helped.
The Holux M 1000C works with BT747!!!

Thanx
