Add call to set Serial options to prevent CR to CRLF conversion

Initial attempt at a fix for #282

Grateful if someone could review, test and advise...

I see that as part of #287 @BenZonneveld would like to merge a private copy of Circle's serial.h, which I would like to avoid if possible, in order not to have the burden of maintenance. Does this PR the same thing that the patched serial.h does in #287?

Yes - this is the way to solve this one. I'm afraid that that change to serial.h has just changed the actual constant definition which has fundamentally changed the options available in the serial driver to remove this! I really strongly suggest we don't do things like that... :)

We should also really discourage slipping in changes like this to unrelated bugs/issues...

Merged this for now; please let me know if the merge causes any trouble for you. Thanks!
