Terminal Server Configuration Without RealPort

Introduction

In this configuration, the Digi device functions as a terminal server, providing telnet and rlogin access to hosts. This configuration enables the following:

• Telnet or rlogin access to the LAN-based hosts, both from the locally-connected terminals and from devices accessing the LAN from the telephone network.
• Access for the LAN-based hosts to the Digi device's ports (sometimes called reverse telnet) and LPD printing to the printer connected to PortServer.

Configuration

set config ip=190.250.150.10 
set ports range=2-3 dev=term
set line range=2-3 baud=9600
set flow range=2-3 ixon=on ixoff=on
set ports range=4-5 dev=mio
set line range=4-5 baud=115200
set flow range=4-5 ixon=off ixoff=off rts=on cts=on
set user name=user1
set ports range=15 dev=prn
set line range=15 baud=9600
set flow range=15 ixon=on ixoff=on 

Configuration Notes

• The set config command configures the IP address and mask for the Ethernet interface.
• The first set ports, set line, and set flow commands configure ports 2 and 3 for terminal connections.
• The next set ports, set line and set flow commands configure the ports for bi-directional modems. Software flow control (the default) is explicitly shut off and hardware flow control turned on using the set flow command.
• The set user command defines a user, which assigns a user name for login purposes. All users can login with this name. Because no password is defined (see the newpass command), the user name functions as a password as well.
• This set ports, set line and set flow commands configure port 15 for a printer using software flow control.
