ABSTRACT:
A communications device is attachable to a host computer. The device transmits, receives, and stores entire files of data with their attributes needed for recognition, reading, and writing by a proper application program. Logical devices such as processors, filters, locks, and telecommunications devices in the communications device include electronic circuits for assembling message files and for transmitting selected datafiles to and from an attached host computer. The communications device also transmits, stores and receives with respect to a second remote device or a computer with a modem. The device permits file communication without permitting access to its own host computer or workstation. The device may transmit while the computer is off, and without logging into the second computer provided with the same type of device. The device facilitates point to point communication of data files in a secure manner for creation of virtual private networks between individuals over public telephone networks.
