WEB/EMULATOR SERVER AND WEB BROWSER TERMINAL EMULATOR FOR PRESISTENT CONNECTION TO A LEGACY HOST SYSTEM OPERATION

摘要

A computer network environment (10) allowing connectionof a client system (36) to a legacy host system (18.19) usinga server (26) is provided. The computer network environmentment' (10) includes a legacy host system (18.19) havingTCP/IP connectivity. The legacy host system (18.19) isoperable to support a terminal session for access to thelegacy host system (18.19). The computer network environ-ment (10) also includes a server system (24) executing aclient thread (25) under a server (26). The client thread (28)is operable to communicate with the legacy host system(18.19) across a persistent TCP/IP socket connection (36).The computer network environment (10) further includes aclient system (36) executing an applet process (42) under aweb browser (38). The applet process (42) is operable tocommunicate with the client thread (28) across anotherpersistent TCP/IP socket connection (44) and is operable toprovide a terminal session to a user of the client system (36).This terminal session is supported by a persistent connectionallowing real-time bidirectional communication with thelegacy host systems (18.19).
