Assuming that the IOLAN+ is being used as a Console server, you will need to dedicate one serial port for modem dial-in. Configure the serial port as follows. Use defaults for values not listed below.
Save & exit then KILL the port to allow changes to take effect.
Make sure to configure your modem for auto-answer. For the IOLAN+ modem cable diagram refer to the Cabling section in the IOLAN+ User guide.
You can use the Windows Hyperterminal program or equivalent. Once you have dialed in and connected to the IOLAN+ serial port, press the enter key and you should see be at an IOLAN login. Login using the default Login password "iolan" and tis will take you to the command prompt. You can now telnet to any serial port by typing the following command:
telnet < Local port number >
For example, suppose the IP address of your IOLAN is 192.168.1.2 and you want to telnet to serial port 1. The default Local port number for Port 1 is 10001. Therefore, you would use the following format:
telnet 192.168.1.2 10001
To telnet to other serial ports simply change the Local port number. The default Local port number for serial port 2 is 10002, serial port 3 is 10003, and so on...
Note: If you configure the Host table in the IOLAN and add the IP address of the IOLAN then you can replace the IP address with a host name of the IOLAN+.
How to disconnect
To disconnect from the session, press ctrl ] (hold down the control key and press the right bracket key).This will return you to the command prompt.
To close the session, type: EXIT. This will return you to the IOLAN Login prompt.
