What's does this name mean?? Nothing. About 15 years ago I was installing a BBS for a friend and was looking for a name for his BBS. I was looking for a computer related name. I thought of "The Comm Port"...nah..All sorts of names with the word "link" in it (BTW, I decided on The AmigaLink BBS for my friends Commodore Amiga based BBS).
Anyway, I liked the sound of "serial port" since it was directely related to computers and BBS's and "port" is a place where ships, or people in this case gather......Then a stroke of genius :-), why not change the spelling of serial to cereal...thats it!
So that's the tale..no hidden meaning..and actually it doesnt mean anything. :-)
