Page 2 Ÿ Introduction
Besides terminals, PortServer serial ports can be configured as modem
ports (incoming, outgoing or bidirectional) or printer ports. These
options require knowledge of your host's operating system to get it to
"see" the devices connected to the ports. For supported operating
systems, Digi's RealPort port control protocol gives powerful control in
accessing the remote PortServer ports.
The PortServer software features extensive help functions. From the
main command shell (entered after login), entering a question mark
("?") brings up a list of commands and descriptions. Entering a
command followed by "?" produces a list of subcommands and their
descriptions.
