What is using COM ports?

By SciFiMan ·
Is there some old Windows command or something in XP Pro that shows what is bound to COM ports?

User laptop running XP Pro having trouble with his Palm cradle serial connection, that there is no port to use. COM4 is his built in modem. He said COM3 was shown but had a little yellow "flag" next to it. He removed COM3, rebooted system still can't get a COM port. COM1 and COM2 show in use but not what is using them. I don't use handhelds........anyone know how to get his cradle attached? It's his personal laptop and Pilot he uses for work so I don't want to tell him to buy USB cradle on his dime.

What is using COM ports?

Don't know if you can sit with user and his documentation for the Palm software but it will prolly help you solve this question.

In my dealings with serial devices that sync with an application I have found that there usually is some setting wrong in the app.

physically look on the computer to see where the cradle is attached. Make note

Double check in the sync app that the com port is correct as noted by 1st step.

Check to see if app has some auto detect funtion < These functions typically malfunction on a serial port connection causing the port to not respond at all when you try a manual update.

It has been my experience that the auto detect funtion in the sycn application causes most of the problems. Check the basics 1st though.
