How to emulate terminal input?

Question

linux

There is a system for centralized collection of network equipment configs - oxidized. In general, it works, with the exception of one nuance - D-Link switches that have RADIUS authentication configured, to access show config, which is required by oxidized to get the config, you need to enter the enable command and then enter a password to elevate privileges. There is a settings file for each vendor, for D-Link it is:

class Dlink < Oxidized::Model
  # D-LINK Switches

  prompt /^(\r*[\[email protected]()\/:-]+[#>]\s?)$/
  comment '# '

  cmd :secret do |cfg|
    cfg.gsub! /^(create snmp community) \S+/, '\\1 <removed>'
    cfg.gsub! /^(create snmp group) \S+/, '\\1 <removed>'
    cfg
  end

  cmd :all do |cfg|
    cfg.each_line.to_a[2..-2].map { |line| line.delete("\r").rstrip }.join("\n") + "\n"
  end

  cmd 'show switch' do |cfg|
    cfg.gsub! /^System Uptime\s.+/, '' # Omit constantly changing uptime info
    comment cfg
  end

  cmd 'show vlan' do |cfg|
    comment cfg
  end

  cmd 'show config current'

  cfg :telnet do
    username /\r*[Uu]ser[Nn]ame:/
    password /\r*[Pp]ass[Ww]ord:/
  end

  cfg :telnet, :ssh do
    post_login 'disable clipaging'
    pre_logout 'logout'
  end
end

Somewhere between show vlan and show config current, you need to emulate such a sequence that oxidized will send to the switch:
enable admin # increase privileges, then Enter # enter a password here that is not displayed, you can just hardcode in
this file, then Enter
zero, I tried to do it by analogy, but it doesn’t work, I’m missing something.
