I've gotten used to the types of busses such as I2C and SPI and
parallel where you have one or more data lines, an optional chip
select line AND A CLOCK LINE. It's so easy to understand - you set the
bit and strobe the clock. The underlying hardware electronics was also
so simple that I was even able to make my own very simple SPI device.
I like to believe that these types of busses are simple, compact, very
stable, fast, and efficient and more immune to errors.

However, the other types of busses which don't use a clock line are
the ones that confuse me. For example, I have no idea how UART
(although I use it all the time), USB and 1-wire work. I would really
like to know how these busses work on the signaling level but I can't
find much information.

If anyone would please enlighten me on the topic or provide some
links, I would very much appreciate it.
