Some BIOSes ( like the IBM PC / AT ) perform the check only for fixed disk / removable drives, while for floppies and superfloppies it is enough to start with a byte greater or equal to < tt > 06h </ tt > and the first nine words not to contain the same value, before the boot sector is accepted as valid, thereby avoiding the explicit test for < tt > 0x55 </ tt >, < tt > 0xAA </ tt > on floppies.

The teleostereograph machine, a forerunner to the modern electronic fax, was developed by AT & T's Bell Labs in the 1920s ; however, the first commercial use of image facsimile telegraph devices dates back to the time of Samuel F. B. Morse's invention in the 1800s.

troff is the major component of a document processing system developed by AT & T for the Unix operating system.

In 1984, the divestiture of the Bell System resulted in the Teletype name and logo being replaced by the AT & T name and logo, eventually resulting in the brand being extinguished.

A pre-standard version of PoC is also defined by the industry consortium made up of Motorola, Nokia, Ericsson, Siemens AG and AT & T Mobility with the aim of creating a commercial offering enabling interoperability between vendors.
