After Linux finishes booting, the gateway is again ready for use.

Operations at the Application Level

The gateway currently has only one factory-installed application, the emu3ap application (an emulator of the A730SD receiver).

Using this application puts you in an environment almost identical to the A730SD receiver.

You can access the emu3ap application in either of these ways:

• Log in as user adv and you are automatically dropped to an emu3ap shell.

• Log in as root and, at the Linux prompt, type emu3ap

In either case, you need to press Enter until you get a message stating that you are in the emu3ap command line interpreter (CLI).

Note: You can reach the gateway over the serial port or over the built-in modem. If the network is enabled (this operation is not described in this manual), you can also reach it over ethernet. You can have several emu3ap processes running at the same time.

Although the emu3ap software and the A730SD are very similar, there are some slight differences in that some commands were eliminated and other features were added.

Commands Accepted by the emu3ap Emulator

As with the A730SD, the emu3ap software supports four different classes of commands:
