559 * a better interface for replacing KD transport modules. Right now, due
560 * to the fact that ntoskrnl is static linked to KDCOM.DLL, the OS loader

562 * loads one of the (hardcoded filenames) "kdcom.dll", "kd1394.dll", or
563 * "kdusb2.dll" modules, and inserts them into the loaded module list under
564 * the name "kdcom.dll". [...]"
568 * This loop replaces a dumb call to strstr(..., "DEBUGPORT=").
569 * Indeed I want it to be case-insensitive to allow "debugport="
570 * or "DeBuGpOrT=" or... , and I don't want it to match malformed
571 * command-line options, such as:
573 * "...foo DEBUGPORT=xxx bar..."
574 * "...foo/DEBUGPORT=xxx bar..."
575 * "...foo/DEBUGPORT=bar..."
577 * i.e. the "DEBUGPORT=" switch must start with a slash and be separated
578 * from the rest by whitespace, unless it begins the command-line, e.g.:
580 * "/DEBUGPORT=COM1 foo...bar..."
581 * "...foo /DEBUGPORT=USB bar..."
583 * "...foo /DEBUGPORT= bar..."
