Subject: [PATCH v3 12/13] USB: ch341: get rid of default configuration
Date: Mon, 11 Apr 2016 01:43:52 +0200 [thread overview]
Message-ID: <1460331833-19836-13-git-send-email-greg@chown.ath.cx> (raw)
In-Reply-To: <1460331833-19836-1-git-send-email-greg@chown.ath.cx>
If the serial port hasn't been opened yet, no baud rate should be
set and RTS/DTR need to be deasserted.
