Using expect to automate mundane tasks

I have a Power5 system I use for testing, no HMC and I cannot always depend on being at a location where I can use the web-based ASMI interface. Plus, I have to wait for the web-interface to load. I prefer to use the serial line connection from tty1 to the serial port of the Power5. But typing in the commands got boring too. Enter expect, a program that can be told what to expect and then send an automated reply.

My program to automatically start a Power5 system

#!/usr/bin/expect -f

 send_user "$argv0 performs 'cu -l tty[lrange $argv 0 0]\n"
 spawn cu -l tty[lrange $argv 0 0]
        expect {
        " DEVICE LOCKED" { puts "*********locked\n"; close; exit }
        "onnected" {
                puts "login to Hypervisor\n";
                send \n;
                }
        "ogin: " {
                puts "**** already active\n exiting\n"; close; exit;
                }
        }
        expect "User ID: " { send admin\n }
        expect "assword: " { send PASSWORD\n }
        expect " 80]: "    { send \n }
        expect {
                " 24]: "           { send \n }
                " 25]: "           { send \n }
        }
        expect "S1> "      { send 1\n; sleep 1 }
        expect "S1> "      { send 1\n; sleep 1 }
        expect "S1> "      { send 8\n; sleep 1 }
        expect "PRESS ENTER TO CONTINUE:" { send \n }
        expect "S1> "      { send 99\n; sleep 1 }
        expect "out."      { send "~." }
        expect "~."        { send "\n" }
        puts "\n\nPower On Successful\n"

ote: you will need to change the PASSWORD to your system admin password.

Below is an example of the output. - And I expect this would work with Power6  and Power7, although the prompts and command option numbers may be a bit different.
