-QEMU Windows COM port filenames not recognized i.e. \\.\COM19 or \\.\CNCA0
-Steps to reproduce:
-1. Run qemu-system-arm with the comand line above.
-2. QEMU fails with `qemu-system-arm.exe: -gdb \\.\CNCA8: '\\.\CNCA8' is not a valid char driver`
-3. ```qemu-system-arm.exe -machine mps2-an500 -gdb \\.\COM19
-qemu-system-arm.exe: -gdb \\.\COM19: '\\.\COM19' is not a valid char driver
-```
-Additional information:
-Windows allows COM ports numbered 10 and higher to be prefixed with a `\\.\` escape as in `\\.\COM17`. Such COM port assignments are not uncommon when a plurality of USB serial adapters.
-Equally problematic are virtual COM port designations such as `\\.\CNCA8` created by the Windows 10x64 driver package known as `com0com`: https://pete.akeo.ie/2011/07/com0com-signed-drivers.html

-Upon checking the source pulled from the Github mirror an initial fix was to simply modify /chardev/char.c, but this appears insufficient. Sadly.
-
-Please ask if more information is required. I am actively working on extending an existing QEMU machine emulation. A patch to fix this problem is below. Please comment if applicable.
