More investigation showed that the message was in-band, just that 
My regexp was broken and lack of ensure was missing :-(

For interest, the main loop looks a little like: 


    flag = false
    begin
      @conn.write("#{cmd}\n")
      str = @conn.waitfor('Match'   => /\$|\>|(to end display)/,
                          'Timeout' => timeout)
      flag = true if str =~ /to end display/    # 'q' needed
      
    rescue TimeoutError
      flag = true

    ensure
      @conn.write("q\n") if flag 
    end 


-mark.
