RealPort software can be installed on one or more host servers to provide local serial port functionality. RealPort can be used to provide standard system COM, AIO or TTY interfaces to control baud rate, parity, stop bits, and flow control of local serial ports. Any system utility or user application that works with a locally attached serial port should work with a Digi PortServer port.
Digi's RealPort software works with both the PortServer and PortServer II products. In RealPort documentation, the term PortServer refers to either the PortServer or PortServer II.
