But wait, there's more! :)
Attached is the martian init script to run martian_modem as a daemon. I
made a slight modification to the command line to enable logging and to
set the permission to 660 on /dev/ttySM0 and changed the group ownership
to "dialout". I then copied it to /etc/init.d, and did an "sudo
update-rc.d martian start 45 2 3 4 5 . stop 55 0 1 6 ." to update the
links.

Only drawback to using it this way is that the martian_modem helper
program puts a 5-7% continuous load on the CPU while connected, dropping
down to a 2-4% load while disconnected. For the desktop machine, it
won't matter so much, but for the laptop it can be a concern in a low
battery situation. Of course, you can always stop the service to save on
battery life.
