【文章內容簡介】 器將處于 “回答 ”模式，但 smartmodem 操作極 為簡單的用戶端通過允許任何數量的 BBS 系統(tǒng)方便撥號。 與原來的 110 和 300 波特的調制解調器在 70 年代晚期， BBS 是特別慢，文件傳輸，通常局限于文本文件（ BBS 系統(tǒng)的列表是一個常見的例子）和小的應用軟件，用于訪問 BBS 通常的終端程序。隨著 1200比特 /秒的耳中引入改進的速度的調制解調 大學生心理咨詢網站的設計與實現 4 preliminary work on the Computerized Bulletin Board System, or CBBS. CBBS went online on February 16, 1978 in Chicago, Illinois.[2] CBBS, which kept a count of callers, reportedly connected 253,301 callers before it was finally retired.[citation needed] Increasing speeds and practical use[edit] A key innovation required for the BBS was the Hayes Smartmodem. Prior to the Smartmodem, modems were almost entirely manual in operation, having developed from acoustic couplers that used a traditional telephone for dialing and hanging up. Such systems were largely useless for BBS systems, because they could not disconnect after the call pleted without the user physically hanging up the phone. The Smartmodem included a small microcontroller that listened for key words in the data, allowing it to pick up the phone, dial numbers, and hang up again, all without any operator intervention. The Smartmodem was not necessary for BBS use, other modems could be left in answer mode, but the Smartmodem made operation dramatically simpler on the user end by allowing the easy dialing of any number of BBS systems. With the original 110 and 300 baud modems of the late 1970s, BBSes were 器 速度提高，這導致人氣大幅增加。對于復雜的 ANSI 和 ASCII 的屏幕和更大的文 件傳輸征稅可用信道容量的需求，這反過來又推動更快的調制解調器的需求。 1200 了 2400的較快，其次是一個延遲在 9600 成為常見的。 9600 甚至沒有設立一個強有力的標準在 kbit / s 的接管。另一個延遲是由于長期的標準流程 發(fā)布之前，只有將很快取代 。 大部分的信息顯示，使用普通的 ASCII文本或者藝術， 雖然一些 BBS 進行高分辨率的視覺格式如創(chuàng)新但不起眼的遠程成像協議。許多系統(tǒng)變得相當復雜的圖形，特別是考慮到該系統(tǒng)僅限于 ASCII 碼。幾個系統(tǒng)試圖模擬圖形用戶界面顯示，只是作為 DOS附加或蘋果系統(tǒng)的出現。可能的圖形演示的最終發(fā)展為南加州大學 bbs 動態(tài)頁面實現（ uscbbs）由蘇珊 biddleb，比 HTML 的動態(tài)網頁的實現。一個完整的 “ 動態(tài)網頁 ”的實現是使用一個均衡的附加展示一個完整的菜單系統(tǒng)分別為每個用戶定制 TBBS 完成。 廣泛的應用和迅速消失 對上世紀 90 年代初，該論壇的行業(yè)變得如此受歡迎，它產生了三 個月的雜志，boardwatch，論壇雜志，并在亞洲和澳大利亞，芯片 N 位的雜志，致力于廣泛覆蓋的軟件和技術的創(chuàng)新和他們身后的人，和上市的美國和全世界的 BBS。 [ 3 ]此外，在美 5 software applications, typically terminal programs for accessing BBSes. Speed improved with the introduction of 1200 bit/s modems in the early 1980s, and this led to a substantial increase in popularity. The demand for plex ANSI and ASCII screens and larger file transfers taxed available channel capacity, which in turn propelled demand for faster modems. 1200 gave way to 2400 fairly rapidly, followed by a delay before 9,600 became mon. 9,600
