PURPOSE:To realize free reception of an input from a console in accordance with the desire of a user, by releasing the input queuing state given from the console with an input of a cross command. CONSTITUTION:A terminal controller 1 is set between a central processor of a center and a terminal device 2 such as a cash handing device, etc. and usually performs a process for transmission of messages between the central processor and the device 2. The controller 1 contains a test switch 10 in order to give a test whether the routes to the center and the device are normal or not. Thus a comparatively small test is carried out with turning-on of the switch 10. Other tests are carried out with a key input applied from a console 3 connected to the device 1. |
