Abstract

A lockout system for preventing children from accessing parentally-restricted and undesirable material with a computer comprises a controller unit for receiving commands from a computer and generating control codes to a data device to transmit electronic information over a phone line. A locking device is operably coupled to the controller unit and has a LOCKED state and an UNLOCKED state. The controller unit is further operable for determining the state of said locking device and preventing the transmission of electronic information from said data device when the locking device is in a LOCKED state. Other embodiments utilize a locking device to disable a relay in-line with the telephone line of a modem or to interrupt the phone line directly.

Claims

1. A lockout system for preventing children from accessing parentally-restricted and undesirable material with a computer comprising:

a controller unit operable for receiving commands from a computer and generating control codes responsive to said commands;

a data device coupled to said controller unit and operable for transmitting electronic information over a line, the data device transmitting electronic information in response to said control codes;

a locking device including a key operated lock switch operably coupled to said controller unit, the lock switch being switchable, with a key, between a LOCKED state and an UNLOCKED state;

the controller unit further operable for determining the state of said lock switch and preventing the transmission of electronic information from said data device when the lock switch is in a LOCKED state;

whereby the transmission of electronic information for the purposes of accessing parentally-restricted material is prevented.

2. The lockout system of claim 1 wherein the controller unit comprises a microcomputer.

3. The lockout system of claim 1 wherein the controller unit is operable for generating dialing control codes for said data device upon the receipt of a dialing command from a computer.

4. The lockout system of claim 3 wherein said controller unit is further operable for preventing the generation of said dialing control codes when the lock switch is in the LOCKED state.

5. A lockout system for preventing children from accessing parentally-restricted and undesirable material with a computer comprising;

a controller unit operable for receiving commands from a computer and generating control codes responsive to said commands;

a data device coupled to said controller unit and operable for transmitting electronic information over a line, the data device transmitting electronic information in response to said control codes;

a relay device positioned in-line with said data line of the data device, the controller unit operably coupled to said relay device for operating said relay device for transmitting electronic information over said line;

a locking device including a key operated lock switch operably coupled between said controller unit and said relay device, the lock switch being switchable with a key between a LOCKED state and an UNLOCKED state, the lock switch, when in the LOCKED state, operable for preventing the controller device from operating the relay device for transmitting electronic information;

whereby the transmission of electronic information for the purposes of accessing parentally-restricted material is prevented.

6. A lockout system for preventing children from accessing parentally-restricted and undesirable material with a computer comprising:

a controller unit operable for receiving commands from a computer and generating control codes responsive to said commands;

a data device coupled to said controller unit and operable for transmitting electronic information over a line, the data device transmitting electronic information in response to said control codes;

a locking device operably coupled in-line with said line, the locking device including a key operated lock switch which is switchable, with a key, between a LOCKED state and an UNLOCKED state, the lock switch being operable, in the LOCKED state, for preventing the transmission of the electronic information;

whereby the transmission of electronic information for the purposes of accessing parentally-restricted material is prevented.
