SYSTEM AND METHOD FOR DETECTING A REMOTE APPARATUS
First Claim
1. A system for detecting a remote apparatus, comprising:
- a host coupled to a network, the host comprising;
a host communication module; and
a virtual port administration module configured to provide a filter rule employed to administrate a remote apparatus; and
a remote interface device comprising;
a serial port connectable to the remote apparatus, the remote interface device comprising;
a device communication module configured to communicate with the host communication module, wherein the host communication module and the device communication module automatically search and connect with each other via the network;
a remote serial port implementation module configured to provide an event notification via the device communication module; and
a detecting module configured to detect the connection status of the remote apparatus using the filter rule, and cause the remote serial port implementation module to send an event notification to the host when the connection status of the remote apparatus is changed.

Abstract
A system for detecting a remote apparatus includes a host and a remote interface device connected to the host via a network. The remote interface device includes at least one serial port configured for connecting to a serial port apparatus. The remote interface device detects the connection status of the serial port using a filter rule provided by the host. When the connection status is changed, the remote interface device sends an event notification to the host. The host adds or removes virtual port objects, which are used by application software and are configured to control the remote apparatus, according to the received event notification. Using the mechanism described above, the host can have remote plug and play feature on a remote serial port apparatus.

11. A method for detecting a remote apparatus, the method comprising steps of:
-
selecting a serial port of a remote interface device; detecting a connection status between the serial port of the remote interface device and a remote apparatus using at least one filter rule that is provided by a host and corresponding to the remote apparatus; waiting for a response message from the serial port; determining the connection status based on the result of comparing the response message and the filter rule; and sending an event notification to the host if the connection status is changed. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
