+description = """The Windows backend serial port in `chardev/char-win.c` always calls `CommConfigDialog()`. This should display a COM port configuration dialog which does (and can) not persist the COM port settings. If the COM port does not support this action (see https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-commconfigdialoga) then the function fails."""
+reproduce = """1. Currently not possible with QEMU releases as QEMU does not recognize extended COM port specifications like `\\\\.\\COM19` or `\\\\.\\CNCA0`"""
+additional = """See https://support.microsoft.com/en-gb/topic/howto-specify-serial-ports-larger-than-com9-db9078a5-b7b6-bf00-240f-f749ebfd913e for details on COM port filenames.
+
+I have a patch which 'fixes' this problem by setting the nominated COM port to defaults of `115200,8,N,0` which seems perfectly sensible in 2024. Please contact me for more details. A git diff shown below (with extensive error reporting)
+
+N.B. Markodown will destroy formatting!
