How Do I Configure Serial Port Correctly?
I just installed a new serial device into my Windows XP machine. It is the
first and only serial device that will be placed on this machine. The device and my motherboard appear to be working fine, as upon initial installation, it worked correctly. However, the problem arises whenever I reboot my machine. Then, I get the following exception: Access to the port 'COM1' is denied. This error makes no sense to me, as it sounds like something else is blocking the port, but I have never had any other serial devices on this machine. I have been able to come up with a strange workaround for this, but it seems ridiculous to me. In order for it to work on the next reboot, I have to first uninstall COM1 in Device Manager before rebooting. I have to remember to do this every time I reboot, or it will not work. I would appreciate any advice you could give me regarding this matter. Is there a tool that would allow me to see what is blocking COM1 at certain times? Or, perhaps, is there a way to automate the uninstall with a script prior to rebooting Windows? |

How Do I Configure Serial Port Correctly?
Go to the Control Panel/System/Device Manager, expand the Ports option and
then double click on the COM1 entry and check the Resources tab for any conflicts listed at the bottom. JS "Marc" wrote in message ... I just installed a new serial device into my Windows XP machine.

How Do I Configure Serial Port Correctly?
It's a SpitFIRE Infrared Remote Control. It uses its internal infrared code
library to support all common TVs, VCRs, DSSs, and DVD Players. Not exactly a mainstream modem like you're probably expecting...I have a physical disability and I'm hoping this will help automate my home a little bit more. By the way, I'm also a programmer. Neither the software that came with the device nor a simple little .NET application I quickly scraped together can establish a connection to COM1 when doing what I described previously.

How Do I Configure Serial Port Correctly?
Some hook is being saved since the serial port is being
reserved , even through a re-boot. I'm not a programmer or even a certified real computer expert. But your suggestion of writing a script sounds good, maybe some real expert can point you to the registry entry for the serial port and change the status from 1 to 0 or whatever is required. Perhaps a program such as TweakUI or FreshUI has a function that can do that. I wonder if http://www.innotechsystems.com/spitfire.htm has a USB driver or if a USB to serial adapter would work?

Can you change to use COM2?

How Do I Configure Serial Port Correctly?
I suppose I could try that. That would involve a BIOS change, right? With
my disability, I don't have quick and easy access to regular keyboard use or plugging and unplugging hardware. I may have to wait for some help to do this. I was hoping I could find a way in Windows to correct this. If I'm having problems with COM1, wouldn't the same issues arise with COM2? "JS" wrote: Can you change to use COM2?

If it is only just a registry setting, that would be easy for me to program.
Do you know of any good registry monitoring software that could compare the two states (working and not working) of my device?

No, I think you just have to do a backup (save a system
restore point) and then look for the registry line. There must be somebody with more experience who can help you.

How Do I Configure Serial Port Correctly?
COM2 uses a different IRQ and I/O resources.
Not sure about a BIOS change, however if the serial device is a card that uses a PCI slot, then the card itself may have a jumper to select which COM port it will use. JS "Marc" wrote in message ...
