After a bit more hunting, I got a lot of infomation here: http://www.opensolaris.org/os/community/os_user_groups/czosug/czosug6_cdma_lite.pdf
However, I'm still a bit confused... Inetmenu nicely saw the script I put in /etc/ppp/peers, but how does it set up the usb pseudo tty that I would put in the script? I'm starting to smell success. This message posted from opensolaris.org
