IER: Interupt Enable Register THR: Transmit Holding Register. The next character to be transmitted is writted here. THRE: Transmitter Holding Register Empty. Triggered when the THR has been written to the I/O device. RLS: Recevie Line Status. Triggered on error. RBR: Receive Buffer Register. Contains the next received character to be read.

Try to follow the existing code as much as possible. Most of it's following more or less the same conventions now.

• Types: LikeThis
• Exported functions: source_file_or_conceptual_unit_then_name
• Local functions: whatever_you_want (must have static linkage! Short names are fine here (1-2 words))
• Local variables: like_this_again (should have short names! :)
• File global variables: s_like_this_with_a_pretty_long_name (must have static linkage, and should have fairly long names- typically several words.)
• Project global variables: Don't. Ever.
• Constants/enum values: LIKE_THIS (note, however, that the enum name is a type, and so should be LikeThis)
