/*
  IBM Secure Attention Key (SAK) Option

  In addition to terminal negotiation, the telnet command allows
  negotiation for the Secure Attention Key (SAK)
  option. This option, when supported, provides the local user with
  a secure communication path to the remote
  host for tasks such as changing user IDs or passwords. If the remote
  host supports the SAK function, a trusted
  shell is opened on the remote host when the telnet send sak
  subcommand is issued. The SAK function can
  also be assigned to a single key available in telnet input mode,
  using the set sak subcommand.

  TN_SAK

  Sends the TELNET SAK (Secure Attention Key) sequence, which causes
  the remote system to invoke the trusted shell. If the SAK is not
  supported, then an error message is displayed that reads:
    Remote side does not support SAK.
