Intelligent data processing terminal having an interlock system |
摘要 |
A set-up store is added to an intelligent data processing terminal for storage of terminal characterizing information therein. Terminal characterizing information includes a representation of installed terminal features and a representation of selected terminal options. The information is changeable by the operator to indicate new installed features or different selectable options. A system of interlocks safeguards against improper operator actions, as follows: An interlock prevents the entry of inaccurate terminal characterizing information. Another interlock disables normal terminal operation if terminal characterization information is not present in the set-up store. A security lock prevents unauthorized entry of terminal-characterizing information. An interlock disables operation of language-unique keyboard keys until a keyboard language has been entered. Another interlock prevents the selection of terminal options unless the installed terminal features are present in the set-up store.
