<p>PURPOSE:To prevent the whole connection control device from being reset when a communicating terminal exists by invalidating the operation of an overall reset circuit when any one of terminal equipment is being communicated with a host computer. CONSTITUTION:When the reset execution of the overall reset circuit is commanded, a communication control circuit 18 judges whether communication is executed or not between the host computer 0 and any one of printers 6 to 8. When the communication is being executed, the circuit 19 is not driven, and only when the communication is suspended, the circuit 19 is effectively driven. The circuit 19 is constituted so as to be driven by a command or an external switch. Consequently, the whole connection control device can be prevented from being initialized during the communication.</p> |
