  • Integrate serial port plug and play into simple signaling communication type UPS
    Patent number: 6785754
    Abstract: In the present invention, a DSR of the serial port is coupled to a DTR of the serial port for responding to a detecting signal from a host computer. A RTS signal of the serial port is at a high level when a system is waiting for a PnP ID information from a PnP device during an enumeration process. The UPS detects that RTS is at high level to determine a time point of delivering the PnP ID information. Hence, the function of serial port plug and play can be integrated into simple signaling communication type UPS.
