How to find what program is in control of your serial port?
(OP)
I am trying to communicate with some control devices using the serial port on a laptop running Win2000. I get an error message which says the problem is some other program is already in control of the serial port. Does anyone know of a program which can be run that will tell me what program is in control? I have tried MSconfig and processes under the Task manager but the cryptic names have been of little use.

Why in the world do you use WINDOWS? Under DOS this --
and a lot of other tasks -- would be simple...

Hotrod, thanks for the tip. If I get access to the guys computer that actually has this problem, I will try that.
I got around this issue by using a USB to Serial converter. It is assigned ports 3 and 4, so there is no conflict.

I'm sorry that I don't know windows too much, but if I were faced with the same situation, I would go to task manager and start blowing away applications (like "fax" machines) and rerunning my application until the offending message went away. Ergo, the last application that I blew away would be the offending task.......

Sorry. I do linux stuff. But it should work.
