I have an application in which, it will query 8 comports. Every time I open a comport, I send it a S, I have a notepad connected to my COM1 then I can see the S that I am writing. Now, if I don't reply to it, it will continue searching through the rest of the comports. By the way, everytime I don't see a reply, I close that port, whichever I happened to open. My problem is that everytime that I open COM3 and send it an S in my read, I see this S coming back??? I do not expect this to happen, what is more alarming is that the que is telling me that there is a byte waiting in my in que. I know that only something being sent by another device can be replying to my S, but what device can be replying back with what I send it? Does the modem behave in this way? Thank you, Neil P.
