Hide cursor on remote terminal

Question

I have an open socket for a remote terminal. Using the answer to force the telnet client into character mode . I was able to set this terminal to character mode.

My question is: how to hide this cursor in a remote terminal using this method?

Answer 1

This is what the ncurses library can do for you.

The curs_set() function can make the cursor invisible.

Answer 2

To deploy mjh2007's answer, the following c / C ++ code will implement sending escape codes to the terminal and read a bit more than raw hexadecimal numbers.

 void showCursor(bool show) const { #define CSI "\e[" if (show) { fputs(CSI "?25h", stdout); } else { fputs(CSI "?25l", stdout); } #undef CSI } 

Answer 3

If your terminal supports ANSI format, you can send the following escape codes :

 Hide the cursor: 0x9B 0x3F 0x32 0x35 0x6C
 Show the cursor: 0x9B 0x3F 0x32 0x35 0x68

Answer 4

If this application is telnet, your application must send IAC WILL ECHO to disable echo on its side. This is useful for entering passwords or if your application is echoing.

 #define TEL_IAC "\377" #define TEL_WILL "\373" #define TEL_ECHO "\001" char buf[4]; snprintf(buf, sizeof(buf), "%c%c%c" TEL_IAC, TEL_WILL, TEL_ECHO); write(sock, buf, sizeof(buf)); 

or

 write(sock, TEL_IAC TEL_WILL TEL_ECHO, 3); 

Hope this helps.
