commonly described as a remote access server. The RAS 1500 performs
five basic applications:
IP Terminal Service

IP Terminal Service
RAS 1500 provides network access for dumb terminals or computers that
emulate dumb terminals. The ASCII data stream to and from these
remote terminals is converted into a networking protocol (telnet, Rlogin,
or ClearTCP) and a session is established with a host to provide an IP
terminal service connection on the RAS 1500’s local network.
