Keyboard/Video/Mouse (KVM) switches ////////////////////////////////////////////////////////////////////////////// Newsgroups: comp.os.vms Message-ID: <3F664335.4E1F1798@intel.com> Organization: Intel Corporation Date: Mon, 15 Sep 2003 15:54:45 -0700 From: Ken Fairfield Subject: Summary: KVMs, LK461 and DECwindows Some time ago, I started a thread titled, "KVM between PWS600au and IBM T20 Laptop". I now have an update and perhaps another question or two. Executive Summary: The Rose Mini-Vista KVM "works" well between a PC running Windows XP and an Alpha running VMS and DECwindows. However, when using an LK461-A2 keyboard, the 6-key editing keypad, function keys F18-F20, and the numeric keypad minus keys are mapped incorrectly on the Alpha, and the top-row functions keys from F13 through F17, and the Compose key, are not available at all. Most KVM vendors support only a standard PC 101/102-key keyboard, but in there higher-end KVM series, Rose say they fully support the LK461 keyboard. Details: I have an IBM T20 Laptop [this is my work platform] plugged into its port-replicator (which allows me to use a standard keyboard, mouse and monitor), and a PWS600au hobbiest system. I wanted to share a sungle LK461-A2 keyboard, 3-button mouse (Digital logo) and Samsung SyncMaster LCD monitor at home through an appropriate KVM switch. The issues that I knew to research at the time were that the laptop (on its port-replictor) wanted the keyboard in mode 2, whereas the VMS (and I think Tru64) want the keyboard in mode 3. The mouse stays in PS2 mode (if that's the right term) for both platforms, and this LCD takes analog input so there were no compatibility problems there either. I found three candidate vendors (there may be more) which would maintain the keyboard in different modes on different KVM ports: Adder, Raritan and Rose Electronics. When I looked into the Raritan, I found it requires a "converter" on any port that runs in other than mode 2, and the cost of the converter plus the KVM was more than I wanted to spend. I almost bought the small Adder 2-port model, but after exchanging some correspondance with tech support at Rose, wound up buying the Rose Mini-Vista KVM. The Mini-Vista comes in two models, one with standard PS/2-MD6 mouse and keyboard connectors and VGA-HD15 for the monitor, and the other with DB25 connectors at the switch for the computer ports. Since the later required Rose proprietary cables, I chose the former...but wound up buying Rose cables for that anyway since you need male-male for the video hook-up which I couldn't find at Fry's. [The Rose cables I bought are nice in that there is a single cable that carries all of the keyboard, mouse and video, but they were a bit pricey.] For reasons that have nothing to do with the KVM, it took a while to get my PWS to the point I could start DECwindows (no, the Radeon 7500 will NOT work with a PWS 600au! :-). When I finally did get to the point of trying to edit in a DECterm, I found that the "Do" key had gone AWOL and that the editing keypad keys had been "shuffled": Keycap Mapped To ------ --------- Find Insert Here Insert Here Find Remove Select Select Prev Prev Remove Oh, and the minus key, "-", on the numeric keypad, mapped to the less-than character, "<". F13, F14, Help, Do and F17 sent nothing to the xev, while F18, F19 and F20 mapped to F13, F14 and Help as viewed in xev. Finally, the Compose key sent nothing. Subsequent correspondance with the three vendors, plus Avocent, Black Box and Linksys, showed that all vendors say the support ONLY 101/102 key "standard" PC keyboards. Except for Rose... The Rose technical support person found explicit referecnces to LK461-xx in his database, one in the german language varient! The low-end Mini-VIsta that I purchased doesn't support the LK461, but the more expensive ServeView Pro and UltraView Pro series of KVMs do! So if you have a situation where you must have full LK461 functionallity, there is at least one vendor out there who can help. Unfortunately, I can't afford $500US for the convenience...although I have been keeping an eye on e-bay... Rose support did say that there is a 1-to-1 conversion from the scan mode 2 to scan mode 3 sequences, and so I suppose there is a possiblity to remap the keys using xmodmap. However, for those keys which didn't send anything to xev, I don't know whether the VMS DECwindows driver is even processing the codes received (Fred???). For the time being, I will plug in two keyboards, one into the switch to be used with the laptop, and one directly into the PWS. I have enough room on either side of my desk to lean the unused keyboard against the side of the desk. :-} I hope this summary helps others who are looking for a KVM that will work with there Alpha VMS systems. -Ken -- I don't speak for Intel, Intel doesn't speak for me...

I also use EDT a lot on my VAXstation-II since it takes TPU so long to start up.

When my client originally bought the MX48, they relied on the promises by Raritan's Western Regional Sales Manager, Jim O'Donnell, that it would work with the Alpha/VMS system. He told us that Raritan supplied KVM switches to DEC and Compaq, and that they had been thoroughly tested to ensure proper operation with Alpha system. When it didn't work, I went through tech support (Don) and got the same story as you did. I than faxed a complaint letter to Raritan's VP of Sales and Marketing, Bob Pollack. The next day, I got a call from Rich Bopp at Raritan who promised to FedEx the APKME modules which, he said, would solve the problem. At first we connected them to both the keyboard and mouse. The keyboard then worked OK, but the mouse was frozen. After a call to Rich Bopp's voicemail, I got a call from Don (no last name) in tech support who suggested connecting it to just the keyboard, which solved the problem. Don also promised to contact me when the new MX48 firmware was ready, which would solve the problem without requiring the use of an APKME module. That was 10-Jan-2001, and I am still waiting. I checked on the Raritan web site and the latest firmware revision is still the same one that came with our unit. DO YOU HEAR THAT, RARITAN? I'M STILL WAITING!

So I'll add my story with the ServeView+ and UltraViewPro from Rose Electronics. I have an LK411-AG (Function keys F1 to F20, full numeric keypad plus PF1 to PF4, four cursor keys and six additional editing keys, 109 in total). I control Macs, PCs and AlphaStations (VMS & Tru64-Unix). What I found so far: I am able to use all(!) they keys under VMS as expected. But after a reboot of the machine I have to connect a real keyboard once to the VMS machines, type a compose character and connect again to the KVM switch.

Likely, your old KVM didn't map ScrollLock to the Sun power button and whatever it did map to that was more difficult to press accidentally. > So I'm curious if there is a way to make the Power > Management ignore the Scroll Lock key, or at least if there was a way to > remap the key to something innocuous. Try editing /etc/default/sys-suspend and change the PERMS variable to be PERMS=- That disallows suspends by anyone except root. Alternately, edit /usr/openwin/lib/speckeysd.map. Comment out the lines that reference "SunPowerSwitch". Restart your X server, including dtlogin. Alternately alternately, remove the power management packages altogether, if you're not using them. I forget the package names right now -- sorry. -- Bitt Faulk //////////////////////////////////////////////////////////////////////////////
