HostAccess is a professional PC terminal emulation software suite currently maintained by Perforce Software. It allows Microsoft Windows users to establish secure connections with legacy, host-based enterprise applications.
The tool acts as a bridge to modernize “green screen” environments without requiring organizations to rewrite their underlying mainframe code. It is particularly prominent in companies utilizing PICK (MultiValue) database systems like UniVerse and UniData. Core Architecture and Capabilities
