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.

Go to www.lavalys.com and download their free program Everest. It should
tell you everything.

Com 1 and 2 were common ports on the backs of old computers.. sometimes they
were two 9 pin D's or one 9 pin and one 25 pin D.. com 1 was invariably used
for serial mouse.. com 2 for external modems or other communications
devices.. modem software setup modems to use the address at com 3 or higher
to avoid conflict with 1 and 2, and for the same reason, other devices would
select higher com ports unless physically connected to either 1 or 2..

Computers generally only have one physical com port these days as USB has
taken over.. it is there in the interests of backwards compatibility.. in
all likelihood, nothing is using the com 2 address.. Everest does not show
com 2 on mine for that reason..
