00:37 <byteit101> headius[m]: Created PR https://github.com/jnr/jnr-enxio/pull/32 and https://github.com/jruby/jruby/pull/5774 for Win LibC . I've only tested it with serial ports on win10 x64 as that is the only windows machine I have access to. Would greatly appreciate if other windows users can verify it.

00:39 <headius[m]> byteit101: cool!

06:38 <byteit101> I got windows IO::sysopen("COM", File::RDONLY) working on my branch (https://github.com/byteit101/jruby/tree/winio) but it returns a fake fileno, whereas MRI returns a real fileno.

06:38 <byteit101> Getting a real fileno from a FileDescriptor is easy enough (msvcrt._open_osfhandle(JavaLibCHelper.gethandle(FilenoUtil.getDescriptorFromChannel(ret))) in RubyIO.cloexecOpen), but I'm not sure where to put the _open_osfhandle ffi definition. Suggestions?

06:47 <headius[m]> Ah well most native IO stuff in JRuby proper is just turned off on Windows because I knew we had no support for it

06:47 <headius[m]> I'll be back on in the morning and we can look at filling this out and getting more enabled

06:48 <headius[m]> Could be a big deal for 9.2.9
