Abstract: A portable computer or a similar electronic device having a wireless data communication device such as a Bluetooth transceiver is provided with a power down procedure activated by a remote control device. For example, a single key remote control device emits a radio frequency signal bearing a power down control signal that is transmitted to the portable computer. The control signal is received by a receiver separate from the wireless communication device and initiates a power down process that first causes the portable computer to wake up from a sleep state, if the computer is in a sleep or similar state. The communication device or the computer then invokes a driver that either directly initiates a power down sequence or that invokes another program that initiates a power down sequence. A log file is written during power down that indicates the state of the computer at the time that the power down control signal was received.

Abstract: A system and method for wireless data transfer between a computer and a telephone line using a remote media interface (RMI). The computer bidirectionally transfers the data to the RMI using an infrared (IR) signal. The RMI acts as an interface between the computer and the telephone line. The wireless data transfer system of the present invention includes an IR transceiver housed on the computer and an IR transceiver housed on the RMI. The RMI includes a data access arrangement (DAA) for converting the data received from the computer into a signal suitable for transmission over the telephone line and vice versa. The RMI also includes an external data interface connected to the telephone line that receives and transmits the signal over the telephone line. A soft modem is installed on the computer whereby at least part of the soft modem uses software to perform the function of a digital signal processor.
