Digi PortServer II User Manual

Page 4 Introduction 90030500B
PortServer II allows terminals to connect to a server using Telnet, Rlogin, or TTY.
Note:
Depending on the terminal type(s), the server may need to be loaded with
Digi International’s RealPort
TM
software to allow the server and its appli-
cations to make full use of PortServer II’s capabilities. See
Chapter 11,
Configuring RealPort Connections
for more information.
•
Local PCs
. Any PC can be connected to a PortServer II serial port. The user has
full access to all applications on the server. Typically, you run a terminal emulator
or SLIP/PPP software package on the PC.
•
Printers
. Any serial printer that supports the RS-232 interface can be connected
to a PortServer II serial port. Parallel printers may be connected via the
PORTS/8emp expansion module.
•
Asynchronous Modem.
PortServer II can provide connections to remote termi-
nals (including terminal emulations), remote PCs, or Internet service providers.
PortServer II supports PPP (Point-to-Point Protocol), SLIP (Serial Line Interface
Protocol), and CSLIP (Compressed Serial Line Interface Protocol) connections up
to 115.2 Kbps.
More detailed descriptions of the features supported for each of these different types
of connection are given later in this chapter.
At the LAN interface, you only require a single Ethernet connection, regardless of
how many serial devices are connected to the PortServer II. Ethernet 10BaseT
(Twisted Pair) and 10Base2 (BNC coaxial Thinnet) connectors are provided.
