T
he 10/100 Serial Server
(LES2700A-100-R3) is a great
way to add serial devices to yo r
mixed Ethernet networks. It
enables yo to add wired or
wireless devices to yo r network
witho t sacrificing host ports or
taking p val able space.
The Serial Server provides
a wide range of protocol and
management s pport. It s pports
TCP/IP, which incl des Telnet™ ,
Rlogin, UDP (User Datagram
Protocol), and DSN (Domain
Name Servers). It also s pports
IPX/IP (NetWare) for downloading
system files and LAT™ (Local
Area Transport) for digital system
s pport.
The server can be sed with
applications on UNIX®, Windows
NT®, OS/2®, or LAT platforms
thro gh a TCP/IP or SPX socket
interface. On any platform, the
host operates with the Serial
Link wired or wireless serial devices
to your Ethernet network.
KeyFeatures
SERIALSERVERS
Server as a directly attached
device, enabling, among other
applications, em lation of a direct
serial connection.
The Serial Server is also
s pported with command
interfaces that enable yo to
config re each nit, connect to
remote services, manip late
connections, or receive feedback.
These general command
parameters are s pported by an
extensive set of stat s display
commands that enable yo to
manage almost every aspect of
the device’s f nction. They
incl de the following:
• Show Host List: Used for
m ltiple host connections;
n mbered 1 to 8.
• Show IPsec rity: Shows
c rrent sec rity tables and
restrictions per address.
• Show NetWare: Displays
information related to IP/SPX
connections.
• Show Ports: Indicates stat s
and config ration of the
serial port.
• Show Server Characteristics:
Displays network-related
server information.
• Show Services: Shows
characteristics of LAT
services offered on the
network.
• Show Sessions: Used to
show active port, ser, and
session type.
• Show Users: This command
displays the name, port
n mber, and connection
stat s of all c rrent sers.
If yo only need 10-Mbps
Ethernet connections, choose o r
10-Mbps Serial Server (LES2700A-
10). It’s compact, so it fits virt ally
anywhere. Like the 10/100 Serial
Server, this basic server works
with a wide variety of protocols
and s pports serial printers. And
