Grant, |

If you have more than one system there, you can set the system to use |
10 |
the serial port as a console. Then run a serial cable into the second |
11 |
system and ssh into it to watch the boot process. Getting the keyboard |
12 |
to work correctly via the ssh --> console-over-serial-port can be |
13 |
tricky so it's best to set it up before you deploy remote hardware. |

Also, I have used a cheap ebedded linux system when the second system |
16 |
is not available. Years ago, I even built a "reboot box"; it was |
17 |
an embedded system with 4 relays and a 2 serial ports connected to different |
18 |
system. I could physically remotely toggle the power. Several companies |
19 |
build these devices, but, I have not used one in years. |

Just find a cheap embedded linux board with a 3-5 VAC(120). |
