Abstract: A computer implemented internal area access communication system is used for communication between internal applications originating internal communication and running in an internal transaction area on a host computer and external applications originating external communication and running outside of the internal transaction area. Included are an external communication module to convert external communication having formats noncompliant with the internal transaction area, a virtual host terminal to run on the host computer and to execute virtual terminal functions associated with language of the external communication that is noncompliant with the internal transaction area and associated with language compliant with the internal transaction area. Also included is an access state controller to route the external and the internal communication based upon the tracked state information for the internal applications.

Abstract: A computer implemented system controls transaction access of requester applications running on end-user computers having network protocol addresses, to internal applications and their associated transactions running in internal transaction areas of host computer systems. Related to each network protocol address, a requester database contains information related to each network protocol address including end-user identification, possible username and password and instructions, possible priority levels of select transactions, and authorized transactions. A listener listens for a connect request from one of the end-user computers. A validator, using the requester database, determines whether the end-user computer has a valid network protocol address.

Abstract: A computer implemented internal area access communication system is used for communication between internal applications (109) originating internal communication and running in an internal transaction area (108) on a host computer and external applications originating external communication and running outside of the internal transaction area. Included are an external communication module (104) configured to convert external communication having formats noncompliant with the internal transaction area, a virtual host terminal configured to run on the host computer and to execute virtual terminal functions (136) associated with language of the external communication that is noncompliant with the internal transaction area and associated with language compliant with the internal transaction area. Also included is an access state controller (102) configured to route the external and the internal communication based upon the tracked state information for the internal applications.
