Expect While Loops - Partial Automation?

I've been reading the O'Reilley expect book and I'm trying to create partial automation for common questions asked on screen in a telnet session and return to interact so the user can resume control.


For example

Code:
while {1} {
     expect {
        -re "What color is the sky?" {send "blue\n"}
        -re "Should you touch a hot stove?" {send "no\n"}
        -re "DNS Server:" {send "4.2.2.1\n}
        -re "##alias" {send "do stuff\nthen stuff\n"}
         interact + return
        }


Can I have an automatic loop that will let me interact with the telnet session and pick up automation when these key questions are asked and will the alias work if I type ##alias in the interact part of the session?


Thanks

NAME
telnetrc, .telnetrc - Specifies setup commands for a telnet session SYNOPSIS
$HOME/.telnetrc DESCRIPTION
The .telnetrc file contains the setup information for a telnet session. It is a hidden file in your home directory and must be readable by the user logging in. The file can consist of multiple entries for each remote host to which a user can connect. A remote host entry consists of multiple lines. The first line is the name of a remote host. The subsequent lines must begin with blank spaces, and contain telnet subcommands. These sub- commands are processed as though they were typed in manually. Lines beginning with a number sign (#) are comment lines. See telnet(1) for a complete list of telnet subcommands. To specify subcommands that apply to all systems, create an entry, using the word "DEFAULT" as the system name, and specify the telnet sub- commands in the subsequent lines. EXAMPLES
The following shows a sample .telnetrc file: # Beginning of telnetrc file # Default subcommands that apply to all systems DEFAULT environ undefine USER # First system entry system1 set echo toggle crlf # Second system entry system2 set echo mode line toggle crlf FILES
User-customized telnet startup values. RELATED INFORMATION
