/*
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.
