Introducing the Communications Server
The Stallion Communications Server (EasyServer II or LantraServer)
is offered in eight and sixteen port models with both Thin Ethernet
and 10BaseT network connectors. The Communications Server allows
serial devices on its ports full access to network services, and it
allows network hosts access to devices on communication server ports.

Communications Server Features
The Stallion Communications Server provides the following features:
HTTP (Web) Service
The Communications Server is equipped with HTTP service allowing the
retrieval of web pages stored within the unit. These web pages
may be accessed using a standard web browser.
Web-Based Configuration
Configuring the Communications Server is simplified by a Web-based configuration
utility. With a web browser and an IP address for the Communications
Server, inputting basic information into a series of screens with plain
language options configures the Server quickly, easily and with reduced
error.
Dial-on-demand
Dial-on-demand lets the Server automatically place calls over public
circuit-switched networks. DOD is an alternative to private leased lines
or packet-switched networks such as frame-relay which may not match
a user's application well and result in higher than necessary costs.
Internet filters
Filters control Dial-On-Demand (DOD) connections. They determine
when to establish a connection, what kinds of network traffic
maintain the connection, and how long a connection will remain
active if there is no suitable network activity.
Flash memory upgradability
Allows the Server's operating software to be upgraded periodically to
newer versions, as they become available. The upgrade is achieved by
a TFTP file transfer from a local network system to the Communications
Server.
Menu support
The menu function allows user-specific menus to be defined by the System
Administrator. The user does not then need to know the command language.
Administrators can create menus with up to ten items.
Remote Ports (EasyServer II)
EasyServer II is the first remote access server to deliver all the potential
of Windows NT Remote Access Services (RAS) to every user on the network.
By putting you on the network as a remote node, EasyServer II lets you
take the office and its resources, with you.
Feature key
The Communications Server has up to 32 optional extra functions (for
example RADIUS support) that can be activated by entering a key.
Command Completion
Command Completion reduces the amount of typing necessary to enter commands
and can give hints about expected command arguments.
Local Mode
Gives users on Communications Server ports direct access to the server
command set. In non-privileged mode, a limited command set is available
to the user. In privileged mode, the complete command set is available
to a user.
Login Accounts
Login Accounts provide enhanced security by requiring a user to enter
a valid user name and password combination to access the Communications
Server. Login accounts also provide an alternate method of starting
PPP and SLIP connections.
Modem Diallers and Dialer Scripts
Diallers make outgoing connections and can also be used as an alternate
method of starting PPP and SLIP connections.
Multiple Sessions
Allows up to eight sessions to run on a single Communications Server
port, and you can switch easily among them.
Online Help and Tutorial
Online help provides syntax and brief explanations of communications
server commands. The online tutorial provides a wide range of information
about how to configure and use the Communications Server. Both
Online Help and Tutorial are also available either from the command
line or from your web browser.
Output Redirection
This feature allows output from the LIST, SHOW, and EXECUTE commands
to be redirected to a file on a remote host via Trivial File Transfer
Protocol (TFTP) or to a local port on the communications server.
Page Memory
Allows the Communications Server to support Wyse terminals that save
and restore a screen image when switching among multiple sessions.
ú PPP and SLIP. The Communications Server supports devices (such
as modems and hosts) attached to ports configured for PPP or SLIP, providing
access to and from these devices over the network. Password Authorisation
Protocol (PAP) security under PPP is supported.
Remote Console
System administrators can access the communications server from a remote
host to monitor and/or reconfigure the Communications Server and server
ports.
Security
The Communications Server provides hardware security and password protection
on all ports and remote logins to the server by means of PAP, CHAP and
RADIUS support.
Session Support Utility (SSU)
All models include software functions compatible with DEC SSU software,
providing multi-session displays on SSU-capable terminals. A special
feature, Turbo SSU, provides a high DNS throughput capability when used
with specially configured Wyse terminals.
Simple Network Management Protocol (SNMP)
SNMP allows a TCP/IP node to query other nodes, such as communication
servers, hosts, and routers, for network statistics and errors. This
information is useful for network management and troubleshooting.
Status Line
The Communications Server supports Wyse terminals that display current
session information on the status line.
TCP/IP
All models support the Telnet and rlogin industry-standard protocols.
Telnet Listener
Ports with printers, UNIX hosts, or modems can be configured as Telnet
listeners and made available to Internet hosts and users on other communication
server ports.
Transparent Printing
Allows local printers attached to terminals on the Communications Server
to print while the terminal is in use.
