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.
