This is usually accomplished through an external "data encryption unit",
which is interfaced between the terminal (host) and modem. It is NOT in
software.

Aside from those very expensive high-end boxes that banks use for
their sensative information, there was a DES encryptor made by Practical
Peripherals years ago.  It still may be available.
