I finally got this working, but I had to compile mgetty on Slackware before I found the problem with Ubuntu. As it turns out, Ubuntu wasn't sending the correct init string to the modem by default. I set the init-chat variable in mgetty.config and things started working right away. For anyone interested, I replied to the howto with my solution in a little more detail: http://ubuntuforums.org/showthread.php?p=2071089#post2071089 On 1/26/07, auditodd at comcast.net <auditodd at comcast.net> wrote: > Haven't tried this myself yet, but it looked interesting: > http://www.howtoforge.com/linux_dialin_server
