I'm trying to connect to my VzW Razr via BT DUN w/o success. My setup works with my laptop w/o issue so I think I've narrowed the issue down to the CHAP authentication issues that others have identified. I performed this edit on my laptop and its a simple fix but I'm lost doing this on my new N770. So far, I get as far as installing/running Xterm and then get root access via the "sudo gainroot" command (I installed becomeroot but I'm not sure that matters or not) but when I enter "vi /etc/ppp/option" its blank. After messing with this for more time than I want to admit, I guess I need noob instructions on how to use vi to edit the file - Mr. T
