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

摘要

The computer network environment (10) of computer allows to connect FTP client FTP (36) to legacy host system (18,19) and uses server (26). Computer network environment (10) includes that legacy host system (18,19) have TCP/IP connectivities. The legacy host system (18,19) is used to support terminal session to access legacy host system (18,19). Computer network environment (10) also includes that server (24) execute client's thread (28) in server (26). Client's thread (28) operationally crosses lasting TCP/IP plug connections (30) with legacy host system (18,19). Computer network environment (10) further includes that client machine system (36) execute applet programs (42) in web browser (38). Applet process (42) can with client's thread (28) another continue TCP/IP trough connections (44) and can operate with provide terminal session to user FTP client FTP (36). The terminal session is supported on the time for allowing real time bidirectional communication lasts and legacy host system (18,19).
