I had this problem. You can't send anything to the serial port when
getty is sitting on it, or getty will think a call is incoming. I solved
this by putting the following two lines at the end of my "/etc/rc.local"
echo "ats0=2" >/dev/tty00
echo "" >/dev/tty00
When rc.local is executed, the getty process hasn't been run yet, so they
don't interfere. The modem is put in auto answer mode, and a little
later init runs getty.
