Serial: Serial read error

[jbarneson]

After upgrading to 0.6.7, my logs are filled with these serial read errors. Maybe this is coincidental to the upgrade and there is a hardware problem. Can anyone shed light on what this error means?

I'm running on a raspberry pi with a USB plm (the wireless, not wired version).

Thanks. Sometimes weird sequences show up by I wouldn't expect to see very many of them. The 2nd part of that message is an error in a logging statement in the code. I've fixed that in the dev branch.
