Com Port in use

[HeavyWater]

Hi all,

Have a problem. Have a windows 2000 pro user that has a terminal application that connects to another computer via com port 1. He was using NT 4 previously without an issue although I never configured it. We had to update his machine to Win2k pro as it was mandated. From within the application, when it tries to connect to the remote computer, an error pops up immediately stating either another instance of the program or another application is using Com 1. I know that there is no other instance of the program running so I'm scratching my head to try and figure out what's using Com 1. He doesn't have Palm software installed either. Not sure if there is an application out there that will tell you what's using the port. In system information - serial ports, com 1, The busy item has a value of -1 and IRQ set to 4. com 2 has a value of 0 and IRQ set to 3. Any help is surely appreciated.

Thanks,

HW

The IRQ's are setup fine, try to uninstall com1 from the device manager, when the computer comes backup it will reinstall the port.
Try the link then

Maybe a port monitor can help you out. And also, there could be a service running in that computer using that port. Maybe the service is running without need and you can shut it down, but you need to know wich one is.
Check if you have any resident program that could be using that port also. A+, MCP, CCNA

I have seen this before it has usually been corrected by disableing an IR port or possilby USB port.
