X-Git-Tag: backups/expat-rbuild@40467~768
X-Git-Url: https://git.reactos.org/?p=reactos.git;a=commitdiff_plain;h=79daaf23031f9d0b4f162254e9328aac6c1d4dfb

Revert code specific to Wine to enumerate serial ports, and allow generic enumeration of interfaces like in ReactOS.
Serial ports will still be enumerated in Wine (using GUID_DEVINTERFACE_COMPORT or GUID_DEVINTERFACE_SERENUM_BUS_ENUMERATOR) if the following registry entries are present:

HKLM\SYSTEM\CurrentControlSet\Control\DeviceClasses\{4d36e978-e325-11ce-bfc1-08002be10318}\COM1
DeviceInstance   REG_SZ     SERIAL\COM1
