Method and system for transferring data to a line connected device using a computer modem |
摘要 |
Systems and methods are described for providing connectivity to portable electronic devices, such as a cordless telephone, for the purpose of upgrading software features. In a preferred embodiment, portable electronic devices can receive incoming data at the PSTN jack from a personal computer that is also connected to the PSTN via a PSTN modem. In this manner, upgrades can be accomplished without requiring users to disconnect the telephone or to connect additional cables or components. The telephone is temporarily disabled from service only during the downloading of the upgrade software from the personal computer to the telephone. Upgrade software can be received at the personal computer from downloads or from other sources.
