R232 port working?

Specs: Windows Vista, 2 GB
Hey, I'm trying to hook something up to my R232 port, but I don't know if it's working it seems I have everything else hooked up fine but the R232 port may not be reading it unsure. Just wondering if there is anyway to test to make sure it's working.

First, verify it is enabled in the BIOS screens. That would be listed as a serial port in there.

Look for a screen (tab) called Integrated Peripherals. As I stated above they will be called serial (or com) ports and there may be two listed. You need to have them enabled. If you need special resource settings that is where you would do that.

There probably is some method to test them but I don't know how, other than connecting hardware and trying it.

Whatever you intend to connect needs to be installed by WinXP. When that happens you will be aware of it. Hardware connected to a serial (com) port must be connected prior to starting the computer.

What is the hardware you want to connect?

Enable in bios to be sure.

Set speed and connection type in device manager, or set mode for dos if dos access.

They make simple loop back test adapters or you can make one yourself.

Otherwise you can test null modem computer to computer. You could even test back to second com port or even lpt port.

"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

What are you trying to hook up?

It will show up in Device Manager as a Com port if Vista recognizes it.

Do you have a Serial mouse?
If so try it connected it to that port - it will work automatically in Vista and while booting if the mboard recognizes it.

Unanswered question - What are you trying to hook up? If it is
an old device or a device without a setup disk, it may need
hardware and/or software handshaking setup. Or the proper
cable. Is the device DTE or DCE?

I figured it all out thanks to everyone for the help, I actually had to go to the BIOS screen, and select 'Auto' instead of what it was originally set at.
