I have an app that I'm attempting to run on DosBox. It accesses com1, which appears to be hard coded in the app. I verified it was com1 using an old machine. Anyway, I can get com1 to open with DosBox, but this particular app gives an error when it tries to access com1. I've tried Procomm and it works fine. I suspect that DosBox is opening the serial port when it launches, and this app is getting a port already open error that causes it to stop. A guess, I can't be sure because the app doesn't report the source of the error. Anyway, is there anyway I can test this? Is there a way I can close the port before launching the app?
Thanks.
