如何模仿CTRL-B到條形碼的功能

Question

這是我在這個網站上的第一篇文章，似乎無法解決問題。

我如何模擬按鍵功能按Ctrl +乙爲條形碼，所以我可以掃描與掃描儀的條形碼不按按Ctrl +乙。 我試過閱讀ASCII控制代碼ASCII control codes 請幫助我。

正如您的一個標籤所示，您已經瞭解了代碼128符號體系。您需要在代碼128B（66）中使用code128A開始代碼（103）和相同的字符作爲小寫'b'。最後，在添加額外的數據後，正確計算校驗和並添加它以及停止代碼（106）。以下HTML說明：

要進行測試，打開寫字板或使用按「Ctrl-B」來切換粗體文本和關閉任何文字處理器。掃描片段中條形碼的打印副本。每次掃描時，您應該看到文本「TEST」在粗體和純文本之間交替。
