NCURSES Programming HOWTO

 

 

In the olden days of teletype terminals, terminals were away from computers and were connected to them through serial cables. The terminals could be configured by sending a series of bytes. All the capabilities (such as moving the cursor to a new location, erasing part of the screen, scrolling the screen, changing modes etc.) of terminals could be accessed through these series of bytes. These control seeuqnces are usually called escape sequences, because they start with an escape(0x1B) character. Even today, with proper emulation, we can send escape sequences to the emulator and achieve the same effect on a terminal window. Suppose you wanted to print a line in color. Try typing this on your console. [via]
