user interface library which provides the menuing system to the text mode configuration utilities bundled with Synchronet. Initially written by Rob Swindell, it was updated by Stephen Hurd to have it make use of the ciolib. It is considered feature complete, so active development occurs only when new features are required. comio is a generic serial (COM) port API implementation for Windows and *nix. It was initially designed by Rob Swindell as part of the SEXPOTS project and was ported to *nix by Stephen Hurd. BBS Utilities SEXYZ SEXYZ (Synchronet External X-Modem, Y-Modem, Z-Modem) is an external file transfer program which supports X/Y/ZModem transfers. It was written to break the reliance on old DOS external protocols such as [F]DSZ and CEXYZ. It supports TCP socket and stdio transfers. It is functional and very little additional development on this is planned. SEXPOTS SEXPOTS (Synchronet EXternal Plain Old Telephone System) is a modem to telnet gateway. It accepts incoming modem calls and forwards them to the BBS via the Telnet or RLogin protocols. SyncTERM SyncTERM is terminal emulator which makes use of xpdev, ciolib, UIFC, and parts of SEXYZ and SEXPOTS. In addition to the platforms supported by Synchronet, it also runs on Solaris and Mac OS X. Supported connectivity options are Telnet, rlogin, SSH, "Raw" sockets, standard modem connections and direct serial connections (using parts of SEXPOTS), and a pty interface on *nix. File transfer options include the ZMODEM, XMODEM and YMODEM transfer protocols (using parts of SEXYZ.) SyncDraw SyncDraw is an ANSI art editor which was initially a cleanup of an old version of MysticDraw. It uses xpdev and ciolib but is not yet complete. It supports the use of TheDraw fonts, and can save to the Synchronet Control-A code format, but is generally considered too incomplete for serious usage. Third-party software The Synchronet project has shown a willingness to "adopt" third-party BBS related software into its CVS tree. Generally, the software is updated to use xpdev and run on the platforms that Synchronet does and then is left in the CVS tree without active development. Domain Entertainment Doors Domain Entertainment was once one of the major companies which wrote addons specifically for Synchronet. Some of their software has since been released as open source and has been imported into the Synchronet CVS tree under the xtrn directory.
