Typewriter the first major typewriter with these features. However, older "nonvisible" models continued in production to as late as 1915. A significant innovation was the shift key, introduced with the Remington No. 2 in 1878. This key physically "shifted" either the basket of typebars, in which case the typewriter is described as "basket shift", or the paper-holding carriage, in which case the typewriter is described as "carriage shift". Either mechanism caused a different portion of the typebar to come in contact with the ribbon/platen. The result is that each typebar could type two different characters, cutting the number of keys and
Not a typewriter Not a typewriter In computing, "Not a typewriter" or ENOTTY is an error code defined in the errno.h found on many Unix systems. This code is now used to indicate that an invalid ioctl (input/output control) number was specified in an ioctl system call. This error originated in early UNIX. In Version 6 UNIX and earlier, I/O control was limited to serial-connected terminal devices, typically a teletype (abbreviated TTY), through the gtty and stty system calls. If an attempt was made to use these calls on a non-terminal device, the error generated was "ENOTTY". When the stty/gtty system calls were
