Host Integrator is always in either remote or local mode. Keeping this check box selected means that Host Integrator can communicate with the host as a terminal; this is known as remote mode. Host Integrator transmits each character typed from the keyboard to the host. As Host Integrator receives characters from the host, it displays them on the screen.
When Host Integrator is in remote mode, but is not connected to a host computer, characters typed at the keyboard do not appear on the screen.
When you clear this check box, Host Integrator can no longer communicate with the host; this is known as local mode. In local mode, Host Integrator does not attempt to communicate with a host computer. Characters entered from the keyboard appear on the screen, but are not transmitted to the host; nor is any data from the host (for example, notification of a mail message) received by Host Integrator.
