Subject: patch "USB: serial: ch341: fix initial modem-control state" added to usb-linus
Date: Thu, 12 Jan 2017 18:18:50 +0100 [thread overview]
Message-ID: <148424153073175@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
USB: serial: ch341: fix initial modem-control state
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

DTR and RTS will be asserted by the tty-layer when the port is opened
and deasserted on close (if HUPCL is set). Make sure the initial state
is not-asserted before the port is first opened as well.
