from the windows xp desktop

For COM1 you would do...
start>control pannel>system>hardware>device manager>PORTS(COM and LPT)
>Communication Port (COM1)>Port Setting>Advanced

Then make sure "Use FIFO Buffers" box is NOT checked.

 

The FIFO buffer window looks like this. Uncheck the buffer box, COM1 and COM2 work best.

It says I need write priviledges for me to change it...

What do I do...

I changed the programming language location so it works now...

 

Login as Administrator.

Mike.

 

Quan

I still cant get it...

 

Quan

How can I get it to program?

What do I need in a complete list...

I am so confused

 

Every XP box has two types of users. Ones with admin permissions and ones without. If you do not have admin permission the you need to ask a user who does (or log in as one that does) and uncheck the "use FIFO" box.

If this does not help then you need to be more specific about what is going on.

 

As is this post. Is the FIFO box unchecked as it should be. If not do not expect it to work.

If it is please post the contents of the BUILD and the MPLAB ICD2 windows. The first is needed to ensure you have built the program correctly. The second will tell us what is going on with the ICD2.

Remember that if it was easy...

 

Quan

Are there 9pin to usb adapters...

I still cant even open the advanced window box...

 

Yes but that is another can of worms. Not all maybe only a few work correctly with an ICD2.

Better to solve the simple problem of unchecking a check mark. Let me create a non admin user and see if I see what you are seeing. Just a few minutes.

IT says:

You must have write priviliges in the registry for this device in order to modify the devices advanced settings.

Hope that helps...

 

I created a user without admin permissions. I get the attached msg box which does not match what you are seeing although they may amount to the same thing.

If you have an admin (not limited) login you should not be seeing anything like your msg or mine.

Do you have an admin/unlimited type login ?

Yeah It says computer administrator.

I dont know what to do. I am so frustrated.

So why isnt it working?

How can I get around this? There seems no other way...

 

If you were not an admin it would look like the attachment.

This is windows XP problem.

Do you have some sort of anti-virus/spyware software that may be protecting the registry? If you have anything of the sort disconnect form the internet then turn it all (anti-software) off and see if you can make the change. It is windoze so you may have to reboot. Be sure to turn it back on prior hooking back up to the internet.

You could try creating another admin user and see if that one will work. Doubtful but it is the only thing I can think of at this time.

The reason you need the FIFO buffer turned off is that when enabled it allows XP to bunch up a lot of info prior to sending it. That is OK for some apps but not anything as real time as a programmer/debugger.

If I can think of anything else I will post again. Maybe another person knows what is going on. I tolerate XP.
