Problems with terminals

see also: Login problems on page 255.

The following section concerns problems with the appearance of data on your terminal screen:

The unit logs me out after a few minutes

•Change the idle timeout value set for the user. The idle timeout for all users is set to 300 seconds (5 minutes) by default, because the unit is designed for remote access connections (using SLIP or PPP).

Corrupt data

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

Missing data

•ensure the same type of flow control is set in both your terminal and on the unit’s port.

Error message ‘not permitted on a dumb terminal’ after typing the cli command ‘screen’

•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 unit 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

•check that the terminal setup in the unit matches your terminal.

•check that entries in the term file match your terminal setup.

•if using a PC/computer, ensure the type of terminal emulation selected in your application matches those supported by the unit. If you still have the problem, you may be suffering with poorly written terminal emulation in your application. Instead use the command line mode; if you have a web browser use JETset.
