Who use my Com Port ?

[Jean-Luc]

Hi,

I have a serial port on my system, com1.

I have also a modem COM3 and a phone adaptaor for synchronization COM4.

COM2 seems to be used by a software but which, i don't know.

How can I define what software is using COM2?

Thanks.

You could try www.Belarc.com or just try System Info. Start>All
Programs>Accessories>System Tools

You could re-configure your BIOS so the on-board COM port
is set to COM2. However, COM ports are multiplexed and you
can only use 1 of a group at a time. (COM1 or COM3 - COM2
of COM4). To avoid problems with COM ports you can buy a
USB to COM port adapter that gives you a dedicated COM
port without the Multiplexing hassles.
