Date: Mon, 17 Mar 2014 09:46:21 +1000
Subject: [PATCH 04/14] tools: rearrange serial settings
If the device was't properly closed/reset after a crash, tcgetattr() will
fail. Ignore that error and apply the settings we want nonetheless, in most
cases the device will just come back normally.
And to do so, merge setting the baud rate together with the rest so we only
have one call. Otherwise we can't apply the baud rate settings without
potentially submitting garbage to the driver.
