MSComm object problem

[aliinal]

In my code i check whether com port is open and if it's not then i open it.

If mscomm1.portopen = true then '1
mscomm1.portopen = false '2
end if '3

mscomm1.portopen = true '4

my code goes like this
but sometimes in line1, mscomm1.portopen returns false so if consition does not run (line2). But in line 4 i get an error like Port Already Open. But even in this error if i debug i still get mscomm1.portopen property false. So i couldn't detect if it's open or not.

What do you advice me to do?
if u wnat i may give you more detail. Thanks

Do you really need to see the state before you open it?
Why can't you just open/close then en masse?

Hi again!

THOMASNG: I need to know the state cus i get an error if it's already open. So i need the real value if it's open or not. If do not check whether that port is in use and directly say mscomm1.portopen=true then i'll get an error msg if other application (e.g. HyperTerminal) is connected to that port. Ok?

I need further help. Cus i think my problem is not easy as you think. But i'm sure that you'll find something to help me if you think again

Thanks for your help
