 BBS "doors" are external online programs, often games, that may be installed on a BBS system for its remote terminal users to use interactively. Doors are usually 16-bit DOS programs from "back in the day" and can be challenging to get working on the computers and operating systems of today. A little patience and the use of pages like this one can usually get them working however.

 The 16-bit DOS component of the Synchronet FOSSIL driver for Windows (all flavors) is called ''DOSXTRN.EXE'' and it is located in the Synchronet ''[[dir:exec]]'' directory. This program [[:faq:win#win64|will not work]] with 64-bit versions of Windows since Microsoft does not include a DOS virtual machine (NTVDM) with those versions of Windows.

-The kernel component of the Synchronet FOSSIL driver for Microsoft Windows 95-based operating systems (**no longer supported**) is called ''sbbsexec.vxd'' and it is loaded when needed by Synchronet automatically. This FOSSIL driver is not actively maintained but has worked well for many sysops and their BBSes for many years. This FOSSIL driver implements the FOSSIL interface only (i.e. does not emulate a physical UART or COM port), so the doors must support and be configured to use FOSSIL interrupts for input and output.

 This FOSSIL driver is also a //virtual UART// driver so that external DOS programs that require COM/UART access for input and output (i.e. do not support FOSSIL), can still be used on the BBS. When supported, doors should be configured to use a FOSSIL interface instead of COM/UART for input and output (for better performance and compatibility).
