Blue Wave is a file-based offline mail reader that was popular among bulletin board system users, especially users of FidoNet and other networks that generated large volumes of mail. It allowed users to download all of their mail and messages, read and edit them offline, and then upload any replies. This reduced the amount of time they spent on line. The name "Blue Wave" originally referred to the client software, but as new clients were written that supported the same file format, the name came to refer primarily to the format itself.

History

Blue Wave developed after Fred Rappuhn and George Hatchew met at a picnic arranged for local area sysops. The two developed the concept at the picnic and started development immediately. Rappuhn concentrated on the offline reader, while Hatchew concentrated on the BBS door program that would convert the BBS message system to a Blue Wave format. The first version was released to the public 20 September 1990, marketed via their company, Blue Wave Software. Doors for most PC BBS systems were made available over time.

Another offline mail packet format called QWK was created in 1987, but only ran on the commercial PCBoard system. It remained less widely used than Blue Wave until new QWK doors appeared covering many of the same BBS systems. The Blue Wave client software was then adapted to allow it to read and write QWK as well as Blue Wave files.

Rappuhn was hired as a programmer by Electronic Data Systems (EDS) in September 1991 and was unable to continue development for Blue Wave Software. Blue Wave Software dissolved and Hatchew started Cutting Edge Computing to continue development. Hatchew was later involved in a serious car accident, and was unable to continue development of the system past 1993.

Description

Like QWK, Blue Wave message files consisted of a selection of seemingly randomly named files. Messages themselves were stored in the main .DAT file, supported by an information file and a file containing the headers for each message, and a pointer to the body in the DAT.

The Blue Wave packet format has also been supported by other offline mail readers such as BlueMail, MultiMail, [1] and Wolverine. A tool called bwave2mbox [2] is also available to convert Blue Wave packets to mbox files.

Y2K

The Y2K date problem hit Blue Wave, like so many other programs. The Blue Wave Reader that the end users use to read their mail exhibited the problem by the addition of a numerical digit leading the TO: name in the header. The Blue Wave Door on the BBS' exhibited the problem by creating three digit years where there should have been a two digit year. Several fixes not directly related to Blue Wave were created but they worked on the actual messages after they had been imported into the local message bases.

In October 1999, Dale Shipp created a fix called BWREPFIX [3] that corrects the problem on the users end. This solution uses a batch file in the archiver section rather than calling the archiver directly. In the batch file, the outbound message dates are fixed and then the batch file calls the archiver which then packs the messages for transmitting to the BBS.

Another Y2K fix [4] was created and released in October 2005. This fix is a patch to the binary date library provided by the Borland International C++ libraries that the Blue Wave Door and Reader programs are compiled with. This fix is considered to be a cleaner solution to the problem because the actual library is repaired internally which means that this method doesn't require any external tools to perform the fixing of the dates.

A bulletin board system (BBS), also called a computer bulletin board service (CBBS), is a computer server running software that allows users to connect to the system using a terminal program. Once logged in, the user performs functions such as uploading and downloading software and data, reading news and bulletins, and exchanging messages with other users through public message boards and sometimes via direct chatting. In the early 1980s, message networks such as FidoNet were developed to provide services such as NetMail, which is similar to internet-based email.

FidoNet is a worldwide computer network that is used for communication between bulletin board systems (BBSes). It uses a store-and-forward system to exchange private (email) and public (forum) messages between the BBSes in the network, as well as other files and protocols in some cases.

Mbox is a generic term for a family of related file formats used for holding collections of email messages. It was first implemented in Fifth Edition Unix.

Synchronet is a multiplatform BBS software package, with current ports for Microsoft Windows, Linux, and BSD variants. Past versions also ran on MS-DOS and OS/2, but support for those platforms were dropped in version 3.0.

XMODEM is a simple file transfer protocol developed as a quick hack by Ward Christensen for use in his 1977 MODEM.ASM terminal program. It allowed users to transmit files between their computers when both sides used MODEM. Keith Petersen made a minor update to always turn on "quiet mode", and called the result XMODEM.

Transport Neutral Encapsulation Format or TNEF is a proprietary email attachment format used by Microsoft Outlook and Microsoft Exchange Server. An attached file with TNEF encoding is most often named winmail.dat or win.dat, and has a MIME type of Application/MS-TNEF. The official (IANA) media type, however, is application/vnd.ms-tnef.

<span class="mw-page-title-main">PCBoard</span> Bulletin board system (BBS) application

PCBoard (PCB) was a bulletin board system (BBS) application first introduced for DOS in 1983 by Clark Development Company. Clark Development was founded by Fred Clark. PCBoard was one of the first commercial BBS packages for DOS systems, and was considered one of the "high end" packages during the rapid expansion of BBS systems in the early 1990s. Like many BBS companies, the rise of the Internet starting around 1994 led to serious downturns in fortunes, and Clark Development went bankrupt in 1997. Most PCB sales were of two-line licenses; additional line licenses were also available.

Mystic BBS is a bulletin board system software program that began in 1995 and was first released to the public in December 1997 for MS-DOS. It has been ported to Microsoft Windows, OS/2, OS X, and Linux. Mystic was designed to be a spiritual successor to the Renegade (BBS) and Telegard bulletin board systems.

QWK is a file-based offline mail reader format that was popular among bulletin board system (BBS) users, especially users of FidoNet and other networks that generated large volumes of mail. QWK was originally developed by Mark "Sparky" Herring in 1987 for systems running the popular PCBoard bulletin board system, but it was later adapted for other platforms. Herring died of a heart attack in 2020 after being swatted. During the height of bulletin board system popularity, several dozen offline mail readers supported the QWK format.

Real-Time Messaging Protocol (RTMP) is a communication protocol for streaming audio, video, and data over the Internet. Originally developed as a proprietary protocol by Macromedia for streaming between Flash Player and the Flash Communication Server, Adobe has released an incomplete version of the specification of the protocol for public use.

Amiga software is computer software engineered to run on the Amiga personal computer. Amiga software covers many applications, including productivity, digital art, games, commercial, freeware and hobbyist products. The market was active in the late 1980s and early 1990s but then dwindled. Most Amiga products were originally created directly for the Amiga computer, and were not ported from other platforms.

The B protocol, or CIS B, is a file transfer protocol developed for the CompuServe Information Service, and implemented in 1981. The protocol was later expanded in the QuickB version and later the enhanced B Plus version. It was a fairly advanced protocol for its era, supporting efficient transfers of files, commands and other data as well, and could be used in both directions at the same time in certain modes. These advanced features were not widely used, but could be found in a small number of client-side packages.

An offline reader is computer software that downloads e-mail, newsgroup posts or web pages, making them available when the computer is offline: not connected to a server. Offline readers are useful for portable computers and dial-up access.

The JAM Message Base Format was one of the most popular file formats of message bases on DOS-based BBSes in the 1990s. JAM stands for "Joaquim-Andrew-Mats" after the original authors of the API, Joaquim Homrighausen, Andrew Milner, Mats Birch, and Mats Wallin. Joaquim was the author of FrontDoor, a DOS-based FidoNet-compatible mailer. Andrew was the author of RemoteAccess, a popular DOS-based Bulletin Board System. JAM was originally released in 1993 in C, however the most popular implementation was Mark May's "MK Source for Msg Access" written in Pascal which also saw its initial release in 1993.

FastEcho is a message processing package for FTN mail systems. It was written and released as shareware by Tobias Burchhardt in 1991. The final version was 1.46.1 which was released in 1997. FastEcho was one of the fastest FTN mail processing packages available for FTN style messages. Running on MS-DOS, DPMI and native OS/2 32-bit, it offered numerous features that were desirable for leafnode systems as well as highend FTN mail distribution hubs.

In computer science, data type limitations and software bugs can cause errors in time and date calculation or display. These are most commonly manifestations of arithmetic overflow, but can also be the result of other issues. The most well-known consequence of this type is the Y2K problem, but many other milestone dates or times exist that have caused or will cause problems depending on various programming deficiencies.

GT Power is a bulletin board system (BBS) and dial-up telecommunications/terminal application for MS-DOS. It was first introduced in the 1980s by P & M Software, founded by Paul Meiners. GT Power can be used both to host a BBS as well as to connect to other BBS systems via its full-featured dial-up "terminal mode". GT Power was a shareware package that required a registration fee in order to access its proprietary network mail transport/handling software and, by default, the GT Power Network. The software is distributed in two "flavors": a terminal-only version, nicknamed GTO, and the full-featured host and terminal version.

<span class="mw-page-title-main">Usenet</span> Worldwide computer-based distributed discussion system

Usenet, USENET, or, "in full", User's Network, is a worldwide distributed discussion system available on computers. It was developed from the general-purpose Unix-to-Unix Copy (UUCP) dial-up network architecture. Tom Truscott and Jim Ellis conceived the idea in 1979, and it was established in 1980. Users read and post messages to one or more topic categories, known as newsgroups. Usenet resembles a bulletin board system (BBS) in many respects and is the precursor to the Internet forums that have become widely used. Discussions are threaded, as with web forums and BBSes, though posts are stored on the server sequentially.
