This is because UNIX serial devices come with lots and lots and lots of built-in software features. Have you ever hit ctrl-C to kill a stuck program? The serial port, even an emulated one in a GUI, does that directly. It has a "send SIGINT when you hit this key" setting.

I am sorry for being blunt first of all. But what you said makes absolutely no sense to me. Why would a terminal need a serial port to function ? Also I have used the terminal in both Debian and Fedora distributions. I have never made any connection to any serial port before using them !
Why would I need to do so ? OSes like Windows also offer ctrl+c combination to kill the program(not that I like comparing Windows and UNIX I am just trying to get my point across). And what do you mean by it does that directly ? How can a serial port send signals to the CPU ?

I am sorry but I don't understand what you are saying probably because I am starting out with UNIX. Do you think I should post a separate thread about this topic dealing with serial ports and terminal devices ? Because its getting off topic here.

In UNIX, you could attach the new drive's partitions wherever you wanted -- /home/ for example, if that particular folder is very big.

If I am not mistaken you mean that you can move around partitions right ? For example I can unmount the /home partition and put it in a different hard disk all together and use it from there right ?
But then why would you call it "partition nesting" ? because that sounds a partition within another partition.

gammu-detect

GAMMU-DETECT(1) 						       Gammu							   GAMMU-DETECT(1)

NAME

       gammu-detect - Gammu device detection

       New in version 1.28.95.

SYNOPSIS

       gammu-detect [OPTIONS]

DESCRIPTION

       Script to detect available devices, which might be suitable for gammu.

       Note   This program lists all devices, which might be suitable, it does not do any probing on devices them self.

       Currently it supports following devices:

       o USB devices using udev

       o Serial ports using udev

       o Serial ports on Windows

       o Bluetooth devices using Bluez

       Note   Supported  devices  depend on platform you are using and compiled in features. You can find out what is actually compiled in by run-
	      ning gammu-detect -v.

       This program follows the usual GNU command line syntax, with long options starting with two dashes (--). A summary of options  is  included
       below.

       -h, --help
	      Show summary of options.

       -d, --debug
	      Show debugging output for detecting devices.

       -v, --version
	      Show version information and compiled in features.

       -u, --no-udev
	      Disables scanning of udev.

       -b, --no-bluez
	      Disables scanning using Bluez.

       -w, --no-win32-serial
	      Disables scanning of Windows serial ports.

OUTPUT

       The  output  of	gammu-detect is configuration file for Gammu (see gammurc) with configuration section for every device which might be used
       with gammu.

       Note   You can choose which section to use in gammu by gammu -s.

       When invoked as gammu-detect -d, also all examined devices are listed as comments in the output.

EXAMPLE

       ; Configuration file generated by gammu-detect.
       ; Please check The Gammu Manual for more information.

       [gammu]
       device = /dev/ttyACM0
       name = Nokia E52
       connection = at

       [gammu1]
       device = /dev/ttyACM1
       name = Nokia E52
       connection = at

       [gammu2]
       device = /dev/ttyS0
       name = Phone on serial port 0
       connection = at

       [gammu3]
       device = /dev/ttyS1
       name = Phone on serial port 1
       connection = at

       [gammu4]
       device = /dev/ttyS2
       name = Phone on serial port 2
       connection = at

       [gammu5]
       device = /dev/ttyS3
       name = Phone on serial port 3
       connection = at

       [gammu6]
       device = 5C:57:C8:BB:BB:BB
       name = Nokia E52
       connection = bluephonet
