Abstract

In display terminal keyboard entry, a system has been developed wherein, in addition to its native or basic operation, the terminal may be used to emulate other terminals so that the terminal may be used as an I/O device to a variety of host CPUs (central processing units). In carrying out such switching, it is necessary that functions represented by the keyboard also be switched. In some cases, situations have arisen wherein a particular key represents the same function for two different terminals being switched one to the other. However, the identical key may be required to be typamatic on one terminal and non-typamatic on the other. Typamatic means that the continued depression of the particular key will result in the repetitive character being printed.
