I was doing it wrong did get it to install, n0w can't get it to work  did it install in the wrong place, it installed under universal serial bus controller and there is no way to check settings there no 9600,n, 1 hardware is not there. Not good at doing this stuff dumb. next step it is on com 1.

well,as I understand it, it emulates a serial port through the USB. But my motto is,if it works,don't try and figure it out.

Hello Sam,

I think this link is also on this forum however i don't know where.

You should have both matching.

However to answer your question in a non technical way Com ports share interrupts.

This was the standard setup way back when the first PC with DOS was released.

It has not changed since then.

You have a chip on your motherboard called a UARTS chip.

This controls the data sent and received.

The interrupts are called just that, they are interrupts.

The firmware in the chip determines how to break a signal that is being sent or received so that it appears to be continuous.

Each of the 15 interrupts have a designated function.

IRQ0=System Timer

IRQ1=Keyboard

IRQ2=PIC

IRQ3=COM port

IRQ4=COM port

IRQ5 =LPT2/Sound card

IRQ7=LPT1 Printer

IRQ8=RTC

IRQ10=Varies/Video card/PCI

IRQ11=Varies/SCSI Cont./PCI

IRQ12=Varies/PS2 Mouse

IRQ13=Numeric Data Processor *

IRQ14= Primary IDE Controller

IRQ15= Secondary IDE Controller

As you can see there are only two IRQs assigned to COM ports.

However some new computers can take over IRQ11 or IRQ12 for COM ports addresses.

Then each IRQ has a unique address.

As there are only two IRQs for COM ports these have to be shared.

You will see COMs 1,3, 5, 7, and so on usually can share the same address.

Also COMs 2,4,6,8 and so on all usually also share the same address.

So it makes no sense what you have. Having Com1 and Com8 sharing the same address.

However i endorse the sentiment that if it is working then leave it alone.

Hope i have not confused everyone?

you not only confused me,but gave me a headache! How are things in the Underworld,Jerry..oops I mean DOWN UNDER? After a 6 month drought we are now getting rain here almost every day.My dog won't go off the porch in the rain. What a dilema.

Sorry about that John, i tried to make it super simple as this part of computers is the most important.

re-reading it maybe it was too high tech,

Today it is 41 degrees CENTIGRADE, no idea what that is in American.

And no rain.

There was a survey on TV this weekend and 69% of voters thought that our ten year drought would break in 2008.

However our CSIRO

http://www.csiro.au/

says that it is going to last another 140 years./

So much for the publics belief in scientific research.

One of my tomatoe plants (middle of summer here) has THREE tomatoes on it after 10 weeks.

When i add up the cost of growing my pathetic plants i would have been better off buy tasteless supermarket ones.

I grow mine just for the fun of it. I can buy much cheaper. But sometimes a guy has to get his hands in the soil...its a good feeling to know that you grew something that you had for lunch.

Sorry about the drought...how ironic that you are surrounded by water and it just has a bit of salt in it so all you can do is use it for fun.
