<p>A method for preventing a hung state of a peripheral (14), the peripheral (14) being connected by a protocol channel through a server (10) to a network (12), and the network (12) having a client (15). For certain types of peripherals, e.g. scanner control language peripherals, the present invention sends a reset sequence to the peripheral (14) and then checks for a data flow between the client (15) and the peripheral (14) during a check data time period. Additionally, the invention sends an unlock sequence to the peripheral (14) after the check for data time period expires. Thereafter, the present invention waits for an insurance time period to expire and then closes the protocol channel between the client (15) and the peripheral (14). The present invention also waits for a response from the peripheral (14). <IMAGE></p> |
