Or use dedicated hardware for the motor controller instead of risking the parallel port because the motors drew too much power and blew out the I/O chip.
That way, you won't have to be doing any privileged I/O (which can only be done in a device driver!), and the SDK that comes with the hardware will make it MUCH easier to control the motors.
A really good example of such can be found here[^].

Good day Dave.
I am already thinking of using the PhidgetMotorControl HC for my robotic tank, but it works out too expensive to buy a seperate controller just to control 4 to 5 servos.
I think the best bet will be to install windows 98SE on my robotic tank. I do a remote login to control my robotic tank, annd do not like Tight/real or any other VNC app.
1.Is there a way to install the Microsoft Remote Desktop app in Windows 98 Second edition?
2.& will all my apps (eg creative webcam NX software & other camera,wireless card,3g Modem software)work in win98 if they work in XP Pro?
Thank you very much for your post.

No. RDC Is an XP or later only feature. There're a number of VNC implementations, you can probably find one that will still work in 9x if you look.

Debatable. 9x support is being dropped in a number of apps and drivers.

Nope, not supported on 9x. You'll have to find a third party solution for that.

Yes, IF AND ONLY IF you canstill find drivers and software that still works on 9x. Since the entire 9x line of Windows was retired, a long time ago, driver and software support has all bust disappeared.
No, the XP drivers will NOT work, nor should they even install, on Windows 9x.

Good day
I installed Windows 98SE last night, and i can not believe i paid for that crap back in the day.
Well at least the app (servo commander) worked like a dream.
You were right, almost no XP apps worked in Windows 98SE, so that means, revert back to XP and try to get direct RAW I/O access to the LPT1 port so the app (servo commander)will work in XP.
David Delaune suggested using PortTalk - A Windows NT I/O Port Device Driver[^] to do this, but i had a look, and it seems very complicated.
Please let me know if anyone knows an easier way to get direct RAW I/O access to the LPT1 port.
Thanks to all you geniuses out there for helping out

It does not get much easier than this:
1.) Download PortTalk[^]
2.) Download Servo Command[^]
3.) Copy the Servo.exe executable into the PortTalk folder.
4.) Right click in the PortTalk folder and create a new shortcut which executes 'allowio Servo.exe /a'
5.) Double-click the newly created shortcut.
In under 30 seconds you could be experimenting with your servo motors. It doesnt get much easier than that.
Note that you will need to execute allowio from an administrative account.
Best Wishes,
-David Delaune

Good day David
Thank you, if the other app fails i will use your method.
I had no clue it is that easy.
Can you perhaps edit Servo commander so that it can control 8 servos, and not just 4 with a mouse or joystick, the topic says control 8 servos, but in the app i can only see 4 sliders?
Thanks.

Good day
Thanks David Delaune, your method worked perfectly.
All i need now is to be able to control 8 servo's with this app, The heading on this page reads "How to control 8 servo motors with a PC ?" http://users.swing.be/philippe.jadin/servoen.htm[^], but i only see four sliders, am i missing something, or is it possible to edit the app to be able to have 8 sliders controlling 8 servo's?
If anyone know what they imply, or if you can edit the app to have this functionality, please let me know.If anyone is good with programming, please have a look at the source code provided in the link, and see if you can get the app to work with 8 sliders.
Thank you guys, i would still be stuck in the stone age if it was not for the great help you guys give.
Have a great day

Yes, you are missing 4 more sliders.
ROVIO wrote: or is it possible to edit the app to be able to have 8 sliders controlling 8 servo's?
The source code would need to be modified, it appears the application was designed to only operate 4 servomechanisms. The reference to the number 8 in the website you provided is most probably referring to DB25 data pins 2 through 9[^].
ROVIO wrote: If anyone is good with programming, please have a look at the source code provided in the link, and see if you can get the app to work with 8 sliders.
Unfortunately the software you are using was developed with Delphi3 which was released way back in 1997. I have not developed anything with Delphi in many years. I *do* however own a copy of Borland Delphi 3 which I havent used in nearly a decade.
Hmmm, I will volunteer to modify the application for nostalgic purposes. You will have to wait until I get off work and I will make an attempt.
Best Wishes,

Good day David
I will appreciate that alot.
Could you please create an .exe file when you are done, because at the moment i have Visual Studio 2008 Standard edition installed, and i have oppened a few source codes, but have no idea what to do with the code to create an .exe file (run file)yet. 
Thank you so much

Visual studio won't compile Delphi. You need the Borland compiler to do that (dunno if there's a free version or not).

Riaan,
It was an adventure and brought back some old pascal memories. I modified the servo application and hopefully added the ability to command 8 servos. I have not tested it at all, I simply modified the source code. Perhaps you should say a short prayer before running it.
You can download it here:
Modified Servo Commander[^]
I can only provide limited support. If you need any additional bug fixes or modifications to the application we can discuss the issue through e-mail. I have included the modified source code and also the porttalk drivers.
Good Luck,
-David Delaune

Good Day David
I have downloaded the .zip file & run the servo.exe file, It looks very good.
I will test the app on the servo,s today after work.
Quick question - Where you put the Hardware Address in the app are those 3 choices 3 different Parralel ports (eg LPT1 / LPT2 /LPT3)
Can i just run the SERVO.exe file, or do i need to do anything something else to run the app.
It works fine here at the office.
Spotted a minor bug in app - when i add the channels 1 - 8 & a few entries down in the table on the right & hit play the blue highlighted box does not seem to move down the list to the next channels down the line & the channels on the left does not move to the corresponding value when it goes down the list.
I will let you know the results tomorrow.
I feel like a kid with a new toy with this app you created. 
I have to say, you did a great job,I an very impressed.
Thank you very much.
My personal e-mail address is riaan.deyzel@gmail.com for direct correspondance.
I do not have your e-mail address, but if you send me an e-mail i will reply to that address.

Good day David
I have not heard from you in a long time, looks like Code project & your job is keeping you very busy.
I would just like to see if you made any progress with the Servo Commander?
I have made allot of progress with my robotic tank, but it will still be better with your new & improved version of Servo Commander.
Please let me know.
Thank you & regards

hi all
Any freeware network simulator tool kit is available for windows and linux ...???/
Regards
Sunny

[Previously: I am not aware of any software that meets your specs. Most network simulators involve some kind of specialized hardware, so you can just put them between both partners and plug them in on either end. For software solutions, you'd probably need a properly configured machine as a bridge, which also has to be fast enough to manipulate the network messages in realtime. That is why there is probably no free solution as well. Yes, you might receive the SW for free, but the specialized box it runs on costs $$$.]
I stand corrected. Randor has provided you with a link, please check it out.
Cheers,
Sebastian

Imagine that you wanted to test how your network software will perform over satellite but the only problem is that you dont have a satellite. Perhaps you wanted to determine how that same software would perform over a dial-up connection. What if your users are complaining that your software crashes everytime network latency exceeds 300ms.

Now you can test all your network software with the super-duper network simulator. And if you call within the next fifteen minutes you will recieve this FREE mouse pad.
