The PortServer II is a high performance communications server allowing the user to connect clusters of 16 to 64 high-speed serial ports to any TCP/IP Ethernet network. It supports asynchronous terminals, modems, printers, and other serial devices. The PortServer II is hardware independent, allowing users to access any type of networked server supporting TCP/IP. As with all Digi terminal server products, the PortServer II incorporates Digi's patented RealPort software which provides local serial port functionality as well as incoming and outgoing Rlogin and Telnet sessions on each port. The Digi Port Authority - Remote (DPA-Remote) gives PortServer II users a management tool for monitoring network and serial activity from a Windows or UNIX-based client or server.
