ASCII清單、名稱、解釋

打印機開發中,對ASCII?(American Standard Code for Information Interchange)的熟悉有助于相關概念的理解。同時深入理解ASCII的相關背景,也可以了解計算發展的歷史。在很久以前的機械打字機時代,CR和LF分別具有不同的作用:LF會將打印紙張上移一行位置,但是保持當前打字的水平位置不變;CR則會將“Carriage”(打字機上的滾動托架)滾回到打印紙張的最左側,但是保持當前打字的垂直位置不變,即還是在同一行。
名詞解釋:
CR:Carriage Return,對應ASCII中轉義字符\r,表示回車;
LF:Linefeed,對應ASCII中轉義字符\n,表示換行;
CRLF:Carriage Return & Linefeed,\r\n,表示回車并換行;
