I think we're losing the plot here a bit. While this is generally useful advice, this thread was originally about the USB serial console port of Cisco ASA firewalls. It should just be a plain ol' USB-to-serial setup. No actual modems of any kind involved, especially not cellular ones. I suspect we shouldn't even be loading umodem at all -- just ucom. But for some reason, umodem gets loaded when I plug the thing in. With just an FTDI serial-to-usb adapter in there, umodem doesn't just, just ucom. These firewalls (and I suspect all of Cisco's newer routers and switches) have both normal serial and mini-USB-to-serial ports, and you can connect a simple USB-to-serial converter (PL2303, FTDI, etc) into the normal port and of course that works fine on FreeBSD. But it would be nice to skip needing the dongle...
