Overview
The Stallion Technologies LantraServer realizes the full capability of Citrix
WINFRAME. A Citrix ICA Client can access the WINFRAME server using a standard
serial interface from anywhere on the network. This allows legacy PCs, PC
terminals, Wyse Winterm terminals, and remote clients to gain full Windows
applications functionality, including Internet access, without the need for a
network interface card (NIC) or any TCP/IP protocol software.
Local clients do not need to connect to the LAN or be placed in proximity to the
WINFRAME server to gain access to the network. Remote clients do not need
WinSock to remotely interface with the network. LantraServer uses its own
TCP/IP transport to create a virtual link between the client and the server,
allowing ICA Clients to take advantage of Citrix’s ICA protocol. This makes
client systems cheaper to install, easier to maintain, and better performing.
LantraServer itself is a standalone remote access server that extends Windows
NT-RAS for remote WINFRAME users through LAN connections. Stallion
LantraServer uses Microsoft NT’s built-in networking and remote access
capabilities to offer an integrated remote access solution.
LantraServer extends the remote access functionality of WINFRAME to any point
on the network. This is achieved by installing the NERP virtual serial driver on a
WINFRAME server. Serial ports on the LantraServer are then mapped transparently
as COM ports. This allows the LantraServer serial ports to be used by any
WINFRAME application or service.
Stallion LantraServer offers all network users ⎯ regardless of location ⎯ features
such as on-demand dialing, multilink PPP, RAS security, integrated Web-based
graphical user interface for setup and support, and the Point to Point Tunneling
protocol that enables the establishment of Intranets, extranets, and Virtual Private
Networks (VPNs).

Requirements
Hardware
K A WINFRAME server
K A Stallion LantraServer with at least one modem
K A client machine with a modem able to dial the LantraServer
K A network linking the WINFRAME host and the LantraServer
Software
K WINFRAME, Version 1.6 or higher, with appropriate service packs
K Citrix ICA Client
K Stallion Virtual COM Port driver, as supplied with LantraServer
Installation
Perform the following steps to set up the LantraServer and configure its serial
ports as WINFRAME COM ports:
To install LantraServer hardware on the network
1. Hardware Installation. See Chapter 2 of the EasyServer II Installation and
Reference Guide for hardware installation and power-on self-test.
2. Enter an IP Address. If your network is configured to provide an Internet (IP)
address using the BOOTP or RARP protocols, the LantraServer determines its
address from the network when you boot up. Otherwise, you need to enter an
IP address manually.
Using the cable provided, connect serial port 1 on the LantraServer to a serial
(COM) port on a WINFRAME or Windows 95 PC. Use a terminal emulator such
as HyperTerminal and configure the COM port to 9600 baud, 8 data bits, 1
stop bit, no parity, and XON-XOFF flow control. Press ENTER until you are
prompted to enter an Internet address. Enter a valid IP address and press ENTER
to accept the default subnet mask.
3. Connect to LantraServer with a Web Browser. When the LantraServer has
a valid IP address, you can use the built-in Web-based configuration utility to
set up the server. Use a Web browser such as Internet Explorer or Netscape to
connect to the LantraServer.
Go to the LantraServer “Home Page” by entering the URL of the LantraServer
in a Web browser on the network; for example, http://123.456.789.001.

To configure LantraServer ports for NERP operation
1. Using the LantraServer Home Page. From the LantraServer Home Page,
click Setup. This dialog box shows a number of subsystems that can be
configured. Click the NERP hotlink.
From the NERP Setup screen, select the LantraServer ports to be configured
for NERP operation and then click Configure. The server set up is now
complete.
2. Using the Command Line Interface. If a Web browser is unavailable, set up
can be done from the command line text interface in Privileged Mode.
To get to Privileged Mode:
K If directly connected to a LantraServer port, press the ENTER key several
times to get to the LantraServer command line.
K If connecting to the LantraServer by the network, telnet to the IP address.
The Enter Name: prompt appears. Press CTRL+Z to get to the command
line. Set Privilege and press ENTER. Enter Password: (system by default).
To set up a port for NERP using the command line:
K CHANGE Telnet Listener 2001 Ports 1 Enabled
K CHANGE Telnet Listener 2001 Connections Enabled
K CHANGE Telnet Listener Raw Mode Disabled
K Logout Port 1
K CHANGE Port 1 Access Remote
K CHANGE Port 1 Flow Control Disabled
Repeat these commands for each port to be configured.
Note
Use Telnet Listener 2001 for port 1, 2002 for port 2, etc.

To install the NERP driver onto a WINFRAME server
The LantraServer diskette contains the NERP virtual serial port driver and
associated software. To install the driver, log on as an administrator and select the
following in the sequence given:
Control Panel
Network
Services
Add
Have Disk
Insert the driver diskette when requested and specify the path to the driver
directory; for example A:\I386. The system then displays the Stallion NERP driver
in the Select OEM Option window. Only one software component is provided, so
simply press OK. The required files are installed on the system.
To create WINFRAME virtual COM ports
You are now prompted to create the virtual serial ports. You can create as many
virtual serial ports as required. The created ports must be allocated in a single
block and cannot conflict with existing serial ports. For example, if you have
COM1 and COM2 installed on your system, you can choose to create four serial
ports starting at COM5. Do this by entering 5 for First Port and 4 for Number of
Ports and press OK.
To map LantraServer serial ports to the virtual COM ports
The NERP Manager − Port Configuration window appears. From here, you can
specify the terminal server port to configure for each WINFRAME virtual serial port.
Select a COM port and click Configure. The Add/Configure Port dialog box
appears. This dialog box contains the following input fields:
K
K
K
K
First COM Port. This is the WINFRAME COM port you want to map to a
LantraServer serial port.
# of Ports. The number of COM ports you want to map to a single
LantraServer serial port. This will always be 1 except in very advanced
situations.
Remote Host Name or IP Address. The name or IP address of the
LantraServer.
TCP/IP Port. This is the Telnet Listener port number that is already set up on
the LantraServer. The numbering scheme starts at 2001 for port 1 on the
LantraServer. Port 2 on the LantraServer is Listener port 2002, etc.

K
Raw Mode and Retry Timeout. Leave this unchecked.
Click OK when complete. The Ports Configuration dialog box reappears.
Select the next COM port and click Configure. Repeat for each COM port.
Press OK to close the window and reboot when prompted. After the system is
rebooted, the configured serial ports are available for use as WINFRAME COM
ports.
System Administration
To add, configure, or remove NERP ports after the initial installation, run NERP
from the Control Panel. Click the Configuration radio button. The NERP Port
Status screen appears.
NERP Manager
Click Add Port, Remove Port, or Configure Port to return to the appropriate
configuration screens previously described. The system must be rebooted before
the COM ports will be available under WINFRAME.
Port Monitoring
To assist in troubleshooting various serial port problems, NERP Manager includes
screens displaying signal status, port statistics, and port set up details. Click the
Status, Statistics, or Settings radio buttons as required.
