推荐答案

扩展键(非字母数字或符号)由单个字符序列组成，序列取决于您告诉 telnet 服务器您所在的终端使用.您需要发送序列中的所有字符才能使其工作.在这里，使用 od -c <<<'CtrlVF2' 我能够看到 \x1b0Q 的序列 使用 xterm 终端.

Extended keys (non-alphanumeric or symbol) are composed of a sequence of single characters, with the sequence depending on the terminal you have told the telnet server you are using. You will need to send all characters in the sequence in order to make it work. Here, using od -c <<< 'CtrlVF2' I was able to see a sequence of \x1b0Q with the xterm terminal.
