Lonnie,

Below is my test script ( I use it for my real ftp, but just tried with
telnet and it seems working )

#!/usr/bin/expect
system "date"
spawn telnet 192.168.249.214 
set timeout 600
expect {
        timeout { puts "timed out when spawning telnet"; exit }
        "connection refused" exit
        "ogin:"
}
send "vu\r"
expect "ssword:"
send "mypassword\r\r"
expect "~]$"
## script ends


Here is the output when I ran it.
