When using a custom baud rate on Linux these lines of code caused it to push a 38400 baud rate setting down into the serial driver (even if temporarily). It would correct this moments later, but we can simply set the BOTHER value at this point. If other platforms have a different default value for ispeed and ospeed when using a custom baud rate, they can define BOTHER as well.
