A TWX or Telex can be hacked just as easily as netmail! All
it takes is changing the answerback.
Nonsense! Both Telex I and Telex II (TWX) are connected to the
Western Union switches via dedicated lines. When you dial a
terminal through the Telex net, you may request its answerback
code, thereby assuring that the message went to a terminal with
the appropriate answerback connected to the appropriate ports on
the Telex net. To forge a Telex one must either change the
terminal address in the Western Union switches (which takes
about a week) or physically fiddle with the telephone lines
which connect Telex terminals. This is far more difficult than
forging a Uucpnet message.
