Problems solved by technology

[0007] However, as mentioned above, in order to interact between the personal hand-held terminal and the host, there is a problem that it is possible to conduct data only when the data synchronization module is installed on the host or the host is equipped with a drive to drive an external storage device. interact
Therefore, if the data synchronization module or the external storage device driver is not installed on the host, the data interaction between the personal handheld terminal and the host cannot be performed

Abstract

A personal hand held terminal has a data sync driver, a USB mass storage driver, and a control section. The control section loads the preset USB mass storage driver or a data sync driver in response to an input command or a request received from a USB host. For example, a system / USB mass storage switchover command is input through a system switchover command key. The control section transmits / receives data to / from the USB host via the USB mass storage driver, if a data transmission / reception request is received from the USB host based on a USB mass storage specification via a USB client interface of the hand held terminal. If the USB host is not provided with a data sync module, it is possible to interface information between both systems, because USB host systems provided with a USB host interface can recognize the personal hand held terminal as a USB mass storage.

Description

technical field [0001] The present invention relates to a personal hand-held terminal, more precisely, to a personal digital assistant with information stored thereon that can be used to interact with a host system and a method thereof. Background technique [0002] Sometimes, a personal handheld terminal such as a personal digital assistant (PDA) downloads new application programs from a personal computer (PC) and installs the application programs thereon, or transfers stored information to other systems, such as a PC. In particular, the personal handheld terminal has the advantage of excellent mobility, but since the information stored in the memory of the personal handheld terminal may be lost due to the limitation of battery capacity or the impact on the personal handheld terminal, it needs to be stable at all times. Back up the data of the personal handheld terminal in the system. In this case, in order for the user to transfer information between the personal handheld...
