Abstract
An improved method and apparatus manages communications port contention and power consumption for a handheld computer, particularly handheld computers with a communications protocol that boosts power consumption when active, such as an RS-232 protocol. The improved method provides communications channel management that automatically opens the communications channel in response to a wake-up signal sent to a handheld computer from a peripheral device. The computer peripheral device is explicitly and/or implicitly identified. The opened communications channel is closed in response to receiving some data from the peripheral device, and/or after a device timeout expires without the handheld computer receiving data from the computer peripheral device.
