Thanks in advance.

we all used to be some time. Welcome to a new realm of mystery and power. ;-)

There are many - USB, SATA, I2C, ... they're all serial interfaces of sorts.
But I guess you mean the traditional RS232 interfaces. They are mapped to ttyS1, ttyS2, ... in Linux.
However, you're probably aware that (regrettably) this kind of interface is dying out. Most modern PCs come without them nowadays, at best, they have a pin header on the mainboard that you could connect to a Sub-D9 jack.
That's why we have to buy extra add-on cards with 2 or 4 serial ports these days, or USB/RS232 converters. :-(

no need to say "sir" - we're on very informal terms here, are we? ;-)

Oh yes, a lot of famous people came from Germany. But from many other countries, too. Mozart and Schwarzenegger, however, are from Austria, even though some people from far away keep mixing Germany and Austria - maybe because we speak very much the same language. Well, Austrian German sounds a bit different from so-called "pure" German, but then again, even within Germany, the various dialects sound very different. People from Hamburg on the North Sea coast, for instance, may have trouble understanding people from Munich in Bavaria. Even some cities in Germany seem to have their own very characteristic dialect, like Cologne, or Mannheim.

Erm, I'm not quite sure (haven't fully understodd the principle yet). As to my understanding, tty0, tty1, ... are virtual interfaces that connect to a console window, for example, while ttyS1, ttyS2 and so on correspond to real, physical ports. Note the uppercase 'S', as Linux is case sensitive in general. TTY (in capitals and without suffix) is just a generic everyday-language-term referering to all these character-based interfaces.
May anybody correct me if I'm wrong.
