Problems with Terminals
Problems with Terminals
The following section concerns problems with the appearance of data on your terminal screen.
The IOLAN logs me out after a few minutes:
z Check the Idle Timer value set for the user. The default setting for the Idle Timer for all users is
0 seconds (does not timeout).
Corrupt data.
z Check your line settings (baud rate, stop bits, etc.)
Missing data.
z Verify that the same type of flow control is set in both your terminal and on the IOLAN’s port.
Error message not permitted on a dumb terminal after typing the CLI command
screen.
z Set your Line to Termtype VT100, ANSI or WYSE60 (or other form of terminal emulation, if
you have downloaded one). The default line type in the IOLAN is
Dumb, which does not support
the graphics characters necessary to view the text-based menus.
Screen corruption when using the text-based menu system.
z Verify that the terminal setup in the IOLAN matches your terminal.
z Verify that entries in the term file match your terminal setup.
z If using a PC/computer, verify that the type of terminal emulation selected in your application
matches those supported by the IOLAN.
When using the function keys on your keyboard, nothing happens or your sessions keep
swapping.
z Change your Hotkey Prefix character. The function keys on the keyboards of some terminals
(like WYSE60) send character sequences which begin with
^a; unfortunately, ^a is also the
default
Hotkey Prefix, which you use to switch between sessions. A valid alternative would be
^b (hex=02). If you are the system administrator, you can change any user’s Hotkey Prefix
character.
When using a downloaded terminal definition, you are having problems using arrow keys.
z Use Ctrl-K, Ctrl-J, Ctrl-H and Ctrl-L for up, down, left and right respectively.
When switching from a session back to the text menus, both screen images are superimposed.
z Press ^r to redraw the screen.
INIT: Error in terminal file <filename>
z This error indicates that you have exceeded the 80 character limit for one or more of the terminal
capabilities defined in the reported file.
INIT: Error on line n in terminal file <filename>
z You have omitted the = sign from the reported line.
Unknown IP Address
You have already configured the IOLAN and you do know your password, but have lost,
misconfigured, or don't know the IP address of the IOLAN, and you cannot obtain a login.
z If the IOLAN resides within the local network segment, you can use DeviceManager to find the
IOLAN.
z You can connect directly to the serial port of the IOLAN, as explained in Through the Serial
Port .
