1. In software, a misfeature that becomes understandable only in historical context, as a remnant of times past retained so as not to break compatibility. example: the retention of ef="module.php?name=Lexikon&file=search&eid=1&query=octal">octal as default base for string escapes in ef="module.php?name=Lexikon&file=search&eid=1&query=C">C, in spite of the better match of ef="module.php?name=Lexikon&file=search&eid=1&query=hexadecimal">hexadecimal to ASCII and modern byte-addressable architectures. See ef="module.php?name=Lexikon&file=search&eid=1&query=dusty deck">dusty deck. 2. More restrictively, a feature with past but no present utility. example: the force-all-caps (LCASe) bits in the V7 and ef="module.php?name=Lexikon&file=search&eid=1&query=BSD">BSD Unix tty driver, designed for use with monocase terminals. (In a perversion of the usual backward-compatibility goal, this functionality has actually been expanded and renamed in some later ef="module.php?name=Lexikon&file=search&eid=1&query=USG Unix">USG Unix releases as the IUCLC and OLCUC bits.) 3. The FOSSIL (Fido/Opus/Seadog Standard Interface Level) driver specification for serial-port access to replace the ef="module.php?name=Lexikon&file=search&eid=1&query=brain-dead">brain-dead routines in the IBM PC ROMs. Fossils are used by most ef="module.php?name=Lexikon&file=search&eid=1&query=MS-DOS">MS-DOS ef="module.php?name=Lexikon&file=search&eid=1&query=BBS">BBS software in preference to the "supported" ROM routines, which do not support interrupt-driven operation or setting speeds above 9600 the use of a semistandard FOSSIL library is preferable to the ef="module.php?name=Lexikon&file=search&eid=1&query=bare metal">bare metal serial port programming otherwise required. Since the FOSSIL specification allows additional functionality to be hooked in, drivers that use the ef="module.php?name=Lexikon&file=search&eid=1&query=hook">hook but do not provide serial-port access themselves are named with a modifier, as in "video fossil".
