微軟的操作系統在歷史上對VT的支持可追溯到 DOS 年代，那時候有一個設備驅動程序名字叫 ANSI.SYS(泄露的dos6.0代碼里面有，位于 ms_dos_6_0_source_code\dos-6.0\dev\ansi，是匯編語言實現的)，加載后就可以讓終端支持VT控制符，后來進入桌面時代后就沒有類似的支持了。直到Windows 10的Anniversary Update(1607)，微軟追加了對VT的支持，這可能是得益于微軟在內核層面支持Linux kernel的努力（WSL）。下面是詳細的介紹和示例內容

那如果windows版本低于win10 1607怎么辦呢？我感覺可以實現一個兼容層，例如微軟的telnet客戶端，他就是支持VT的，查看前一段時間nt5泄露代碼，確實找到相關的代碼。

位于?F:\nt5src\Source\Win2K3\NT\net\tcpip\services\telnet\client\trmio.c

代碼非常多，簡單摘一些里面代碼聲明吧。

static UCHAR pchNBBuffer[ READ_BUF_SZ ]; static void NewLineUp(WI *, TRM *); static void NewLine(WI *pwi, TRM *); static void SetBufferStart(TRM *); static BOOL FAddTabToBuffer( TRM *, DWORD ); static BOOL FAddCharToBuffer(TRM *, UCHAR); static void FlushBuffer(WI *pwi, TRM *); static void CursorUp(TRM *); static void CursorDown(TRM *); static void CursorRight(TRM *); static void CursorLeft(TRM *); static void ClearLine(WI *pwi, TRM *, DWORD); static void SetMargins(TRM *, DWORD, DWORD);

另外微軟win10 的cmd和conhost是開源的，在

https://github.com/microsoft/terminal

搜索?ENABLE_VIRTUAL_TERMINAL_PROCESSING 可找到相關的代碼
