Login Problems

Login Problems

You cannot obtain a login on any of the serial ports

zConnect via the Admin port and check the settings of the front-mounted ports; they have probably been set to a profile that does support serial connections, such as the Console Management profile (in CLI or Menu, ‘direct’ or ‘silent’ telnet/rlogin). Try setting the serial port(s) to the Terminal profile (DSlogin in CLI or Menu).

You have lost or don't know your password (as Admin user).

zYou must reset the IOLAN to its factory default settings using the Reset switch on the rear panel. There is no procedure to access the IOLAN without a password.

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:

zCheck 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.

zCheck your line settings (baud rate, stop bits, etc.)

Missing data.

zVerify 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.

zSet 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.

zVerify that the terminal setup in the IOLAN matches your terminal.

zVerify that entries in the term file match your terminal setup.

zIf 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.

zChange 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.

zUse 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.

zPress ^r to redraw the screen.

zThis 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>

zYou have omitted the = sign from the reported line.
