Sender: monopoly MN Do you still need to bring fish fillets when you come back during the National Day? Message area: BBS Help Title: Terminal Experience Journey 3 Sending site: Sun and Moon Guanghua September 18, 2005 13:28:37 Sunday, site mail In order to know the strings sent by these special keys, let's think of a way Make the key combination string starting with <Esc> a visible string In editing mode, press <Esc> and then press <PageUp>. What will appear? Yes, it is *[5 An <Esc> sent when <PageUp> is pressed together with the <Esc> we specifically pressed before Let the system return * followed by the string sent after <Esc> when <PageUp> is pressed [5 Therefore we can infer that the string sent by the keyboard to the system when <PageUp> is pressed is ^[[5 Although we have tested and know the specific strings sent by the terminal to the server after pressing these special keys, But we don’t yet know what specific string the keyboard sends to the PC host The keyboard is a standard input device and there should be a definite and unique standard. Please help me first. The same function key is sent to the BBS server via different terminals, possibly in different forms. But no matter which terminal sends the form, it will have the same effect when used in other terminals. The following list is only tested under WinXP Telnet and Sterm 2.549 Fterm 2.5.0133 Cterm 3.21 beta2 Not tested with other terminal types or versions All special keys start with ASCII character No. 27 sent by <Esc>. In the table below, the reverse escape is ^[ Key Telnet Sterm Fterm Cterm Other allowed substitution keys Esc ^[ ^[ ^[ ^[ Home ^[[1 ^[[1 ^[[1 ^[[1 ^[O1 Insert ^[[2 ^[[2 ^[[2 ^[[2 ^[O2 Delete chr 127 ^[[3 ^[[3 ^[[3 ^[O3 End ^[[4 ^[[4 ^[[4 ^[[4 ^[O4 PageUp ^[[5 ^[[5 ^[[5 ^[[5 ^[O5 PageDown ^[[6 ^[[6 ^[[6 ^[[6 ^[O6 ^[[A ^[OA ^[[A ^[[A ^[[B ^[OB ^[[B ^[[B ^[[C ^[OC ^[[C ^[[C ^[[D ^[OD ^[[D ^[[D F1 ^[OP ^[OP ^[[11 F2 ^[OQ ^[OQ ^[[12 F3 ^[OR ^[OR ^[[13 F4 ^[OS ^[OS ^[[14 F5 ^[[15 ^J <Null> F6 ^[[17 ^[[17 ^[[17 F7 ^[[18 ^[[18 ^[[18 F8 ^[[19 ^[[19 ^[[19 F9 ^[[20 ^[[20 ^[[20 F10 ^[[21 ^[[21 ^[[21 F11 ^[[23 ^[[23 ^[[22 F12 ^[[24 ^[[24 Ctrl F1 ^[OP ^[OP ^[[k Ctrl F2 ^[OQ ^[OQ ^[[l Ctrl F3 ^[OR ^[OR ^[[m Ctrl F4 ^[OS Ctrl F5 ^[[15 ^J <Null> Ctrl F6 ^[[17 <Null> ^[[p Ctrl F7 ^[[18 ^[[18 ^[[q Ctrl F8 ^[[19 ^[[19 ^[[r Ctrl F9 ^[[20 ^[[20 ^[[s Ctrl F10 ^[[21 ^[[t Ctrl F11 ^[[23 ^[[23 <Null> In addition, the following are global shortcut keys under the Windows XP operating system Ctrl Esc Win key Ctrl F12 ^C Some special keys have no response and are listed with <Null> in the above table. Some special keys are used for special purposes in the terminal software and cannot be sent to the server. They are listed with in the table above. The strings sent by these special keys all start with ^[[ or ^[O. This is also called the internal code input method. to be continued Reprint: Sun and Moon Guanghua bbs.fudan.edu.cn [FROM: 10.100.111.111] Modification: monopoly modified this article at 14:25:08 on September 18th [FROM: 10.100.111.111]
