- FOSSIL
FOSSIL is a standard protocol for allowing serial communication for
telecommunication s programs under theDOS operating system . FOSSIL is an acronym for "Fido Opus SEAdog Standard Interface Layer". "Fido" refers toFidoBBS , "Opus" refers toOpus-CBCS BBS, and "SEAdog" refers to a Fidonet compatible mailer. The standards document that defines the FOSSIL protocol is maintained by the Fidonet Technical Standards Committee [ [http://www.ftsc.org/docs/fsc-0015.001 FSC-0015] — FOSSIL implementation and use, Fidonet Technical Standards Committee] .A "FOSSIL driver" is simply a communications
device driver . They exist because in the early days of Fidonet, computer hardware was very diverse and there were no standards on howsoftware was to communicate with the serial interface hardware [ [http://www.ddj.com/cpp/184403026 Dr. Dobb's] — Interfacing to a FOSSIL Communication Driver, Dr. Dobb's Journal] . Initial development ofFidoBBS only worked on a specific type of machine. Before FidoBBS could start spreading, it was seen that a uniform method of communicating with serial interface hardware was needed if the software was going to be used on other machines. This need was also apparent for other communications based software. The FOSSIL specification was born in 1986 [ [http://sysopworld.com/bbsfaq/ch06.09.htm SysopWorld] — The History of FOSSIL Drivers, The Official BBS FAQ] so as to provide this uniform method. Software using the FOSSIL standard could communicate using the same interrupt functions no matter what hardware it was running on. This enabled the developers to concentrate on the application and not the interface to the hardware.FOSSIL drivers are specific to the hardware they operate on because each is written to fit specifically to the serial interface hardware of that platform. FOSSIL drivers became more well known with the spread of
IBM PC compatible machines. These machines ran some form of DOS (Disk Operating System) and theirBIOS provided very poor support for serial communications—so poor that it fell far short of the needs of any non-trivial communications task. Over time,MS-DOS andPC-DOS became the prevalent operating systems and PC compatible hardware became predominant.Two popular DOS based FOSSIL drivers were
X00 and BNU.A popular Windows based FOSSIL driver isNetFoss , which isfreeware .References
