ILVideo80 "HP 92198" : how it works?

Postby floppy_stuttgart » Tue Apr 05, 2022 8:14 pm

Hello,
the extract below is from the help file.
What happens on a Windows machine when using ILVideo80 and using the hotkeys T and M? A window is poping up?
How does it work? any commands must be used? I dont know the behaviour because I never had an "HP 92198" (I will try to find a manual of it).
Any advice is welcome.
I try to make it working on a linux 64bits started by "wine" and I am having still few issues with hotkeys therefore configuration file therefore.

Code: Select all
TCP/IP Setup...

ILVideo80 has an integrated TCP/IP server for receiving HP-IL frames from the preceding device and a TCP/IP client to transmit IL frames to the next device. This implements a virtual HP-IL over a PC network.

Choosing TCP/IP (IPv4/IPv6) as transport protocol gives the advantage of communicating with virtual HP-IL devices around the world if the host PC has access to the internet. Each virtual HP-IL device contains a TCP/IP server listening for data frames on the specified port number and a TCP/IP client sending data frames to a port of the next virtual device. A HP-IL data frame is normally 11 bits long, but as TCP/IP is a byte oriented protocol it is mapped to 16 bits (2 bytes). The remaining upper five bits are filled with zero (reserved for future use). The two bytes of a frame are transferred in network byte order.

Therefore you have three virtual HP-IL mode parameters:

    Out TCP/IP Address

    The "Out TCP/IP Address" identifies the host PC with the next virtual HP-IL device. If the next device is on the same computer use "localhost" or "127.0.0.1" for IPv4 or "::1" for IPv6 as TCP/IP address, otherwise the DNS name or the TCP/IP address of the next computer. (A device may be a simulated device or an IL frame sniffer.)
    Out Port (49152-65535)

    The TCP/IP Port number represents in the simulation a physical HP-IL cable. It must have the same number as the "In Port" of the subsequent device on the virtual IL.
    In Port (49152-65535)

    Here you must enter the same number as on the "Out Port" of the previous device on the virtual IL.

So each device is listening for HP-IL frames on it's in-port, processes the frames inside the device simulation, and send output frames to it's out-port.

The Port numbers are split into three groups:

    Well-known ports: 0-1023
    Registered ports: 1024-49151
    Dynamic, private or ephemeral ports: 49152-65535

For virtual IL you should use port numbers from the third group (49152-65535). Port numbers below 49152 are also accepted.

Open TCP/IP ports are nowadays a security problem when your PC is connected to the Internet. To protect your computer from unauthorised requests all modern operating systems contain a (personal) firewall which blocks attacks. By default all ILVideo80 TCP/IP traffic is being blocked too. Depending on your firewall you are asked at first usage of ILVideo80 in TCP/IP mode to permit the communication or you must beforehand enable manually the ILVideo80 program in your firewall. For security reasons you should restrict the rights of ILVideo80 to the local PC or not more than to the local LAN.

To set the above mentioned virtual HP-IL mode parameters call the "TCP/IP Setup..." item in the ILVideo80 system menu (you get it by Alt+Space Bar or a left mouse click on the symbol in the top left corner or a right mouse click on the title bar). After you finished the setup, press the "Start" button please. If the "Start" button is disabled, the virtual HP-IL interface is already running. So you have to "Stop" and restart the interface for activating the new settings.
Monitor Type Setup...

To set a new monitor type call the "Monitor Type Setup..." item in the ILVideo80 system menu (you get it by Alt+Space Bar or a left mouse click on the symbol in the top left corner or a right mouse click on the title bar). You can choose between

    Black & White
    Green
    Amber
    Custom

monochrome monitors. For the Custom monitor type you can freely define the fore- and background color, the other three types have preset values.

I have an HP92198 and the manual, and I've also kept Intel Hex image files of the EPROMs' contents. I should scan the manual and send the whole set to Warren to put on the site, along with the EPROM images. A cool thing about the EPROMs is that you could change the contents of one of them to change the character set. I won't be able to put it all together today or even this week though. Until I do, do you have questions about something in particular I could look up for you? I have only used the 92198 basically as a printer, to list things to view temporarily without consuming paper. It does have a lot of escape sequences though to allow the editing facilities you would expect in a product like this.

LOL -- now I see. Those underscores mark the accelerator keys of the system menu. They are at call when the dialog window's system menu is displayed.

And? what happens usually when the keys are pressed?

There are no "hot keys" to open those settings dialog, you access them from the system menu (click in on the button at the left end of the title bar) and then you can click on the various settings choices. When the system menu is open, pressing "T" will indeed open the TCP/IP settings, but I did not find a key to open the Monitor dialog; since you use the mouse to access the system menu anyhow, you may as well just click on the setting menu choice you want.

The manual for the 80-Column display interface can be found here: http://www.hhcworld.com/files/compendiu ... manual.pdf

I suggest you also look at Sylvain Cote's "HP-IL Compendium", easily the best single resource available on HP-IL devices, usage, programs, etc.

"click in on the button at the left end of the title bar": I dont see this. See attachment.
Looks like few things are missing? (no system menue etc.)

Did you ask, what happens usually when the keys are pressed? This question has nothing to do with HP-IL, right? You ask about some fundamental handling of Windows applications running under a Windows-OS. Right? So your query is pretty much similar asking what happens if you press the button of a door bell. Answer: usually nothing unusual.
All answers about using menues under Windows could be solved here: https://docs.microsoft.com/en-us/windows/win32/menurc/about-menus But it looks as if you are using WINE, what spells WINE Is Not an Emulator. That's all I know about it. Well, also this -- it has nothing to do with HPIL.

As Mike says, the issues you're having are unrelated to the HP/HP-IL, etc. aspects and are fundamental Wine/Windows issues.

Try holding down Alt- and press the space bar - this should open the system menu, but it does not work on 100% of programs, and I've no idea if Wine will past that through it's layers to the application program. If not, then I'd look for help from the Wine community or locate a FAQ for Wine users, etc.

Good luck
