Hi, I have an windows application sending and receiving data from COM port. The app. works fine with PCI card/serial cable but has problems with certain brand of USB-to-Serial cable. In that case, random system crash happens with blue screen. Take a look at the blue screen and check the minidump file, it points to ser2pl.sys, which is the usb-to-serial driver.
I want to check what really happens to crash the serial driver and want to how to analyze the kernel dump file to find out the root cause. maybe my application could make some changes to get around this. Any help or hint will be appreciated. thanks,
