The Question is: dear sir.. i have an alpha server 4100 with OpenVMS V7.2-1 installed.. and a dw-motif V 1.2-5, i registered and loaded the required license.. but the windowing doesnt work... and all the time an error on OPA0: (error modifying OPA0:) (unknown terminal type) device always appears..and i can't edit any from the main monitor.. the command $set term/inquir does not response.. the monitor type is COMPAQ V70 ANY IDEA ABOUT THIS PROBLEM thanks alot for your cooperation The Answer is : The Alpha console environment is very primitive and (at best) some of the available systems can emulate a VT52-series terminal. The workstation requires the windowing system and the graphics controller to drive the displays and for tasks such as an emulation of a terminal display -- in the vast majority of cases, the interpretation of and the processing of character data is a task that is performed by host software. The (incomplete) listings of the errors seen would tend to indicate something in a login procedure or an interactive command or such, and not something in DECwindows itself. Now that you have the necessary licenses installed, log off the console and start up DECwindows. (If you cannot, then -- since you have already inserted the DECwindows startup into the system startup and since you have already set the WINDOW_SYSTEM parameter per the FAQ, you can shut down and reboot the system.) The configuration and use of a standard serial terminal or a terminal emulator as a serial console can be advantageous -- details on setting up a serial console are included in the FAQ. This approach bypasses the rather limited and primitive environment of the console and the workstation graphics controller. The graphics monitor itself is irrelevent to the discussion of the display capabilities, the capabilities are dictated by the graphics controller and the host software. The graphics monitor itself -- unlike a traditional serial terminal or a terminal emulator -- imparts no intelligence and no capabilities beyond the simple ability to display the signals generated by and received from the graphics controller. The graphics controller and the host are thus the key components. (The FAQ has a tangentally related discussion, on matching the graphics controller signaling with the graphics monitor.) Details of installing and configuring DECwindows are included in the DECwindows documentation set. This documentation -- including the DECwindows installation guide -- is available at the OpenVMS documentation website.
