Is it possible to attach an out of band modem to the aux port on an asa 5500? If so what are the commands as I have been unable to locate any?
Thank you.

I have not physically seen one, but all other Cisco devices have a serial console port.   You can hook up a modem to this.

I have not tried connecting the modem to the auxiliary port. However an option is to use the out of band management port to connect to a Desktop and dial in to the desktop and get the access to the ASA. One more option is to have a Cisco 2511 Access server which can manage not only ASA but any cisco device, that too by console.

The ASA has four eth ports, a console and an aux port along with USB ports. I would like to connect a modem for oob just like you would do for a router. Is that possible?

Just like a router you should be able to connet a modem to the console port or AUX port using a RJ-45 with a DB9/DB25 connector on the other end.

Unlike a router the aux and con ports do not show up in the configuration.

There is no sh line command. If you execute it you get an error.

It looks like you may not need to configure it.  You just connect a cable with the correct pinout to the AUX port and to the modem (or terminal)  with the settings 9600-8-n-1 just like you would to the console port.
