| $0: Connect a modem to a debug server running on a remote machine. |
| |
| As a convenience, configures the ethernet interface to an |
| AUTOIP address so that the interface can connect with a device hooked |
| directly to it over an ethernet cable. |
| |
| Examples: |
| $0 169.254.54.76 |
| Configures ${DEFAULT_IF}'s IP address to $DEFAULT_IF_IP and connects to |
| 169.254.54.76 |
| $0 169.254.54.76 --noconfigure_interface |
| Just connects; does not configure the interface. Use this if |
| you are not using a direct ethernet connection |
| |
| If the connection is working, you will see hex dump data flying by. |
