I'm using pppd to keep a full-time connection to my ISP so my site will stay up 24/7, and my command line is just: pppd /dev/cuaa1 115200 (you can use 57600 in place of 115200 if you like). Either way, all the rest of the info for dialup comes from the file /etc/ppp/options. This includes the chat line, as well as a number of assorted options. Check the man page on pppd; it's long, but it does have the info. Hope it helps, Ken
