Question

I want to make Putty recognize shift arrow sequences

as i know for example ^[[A means up and ^[[1;2A is shift+up

I’ve modified putty source code as following

            if (shift_state == 1)
                if (app_flg)
                    p += sprintf((char *) p, "\x1BO1;2%c", xkey);
                else
                    p += sprintf((char *) p, "\x1B[1;2%c", xkey);
            else
                if (app_flg)
                    p += sprintf((char *) p, "\x1BO%c", xkey);
                else
                    p += sprintf((char *) p, "\x1B[%c", xkey);

instead of

                    if (app_flg)
                        p += sprintf((char *) p, "\x1BO%c", xkey);
                    else
                        p += sprintf((char *) p, "\x1B[%c", xkey);

by running cat -vt putty seams to provide correct key code to terminal but in emacs i still can’t shift select text (instead it puts text ;2A for up etc.)

running begPutty which already contains this fix (also i don’t have source code for it) cat -vt prints the same key codes when using shift arrows and works fine in emacs.

Basically i want to implement begPutty functionality fixes for keycodes but i don’t have it’s source code

I’ve added emacs as a tag as my opinion is that the problem is in emacs not recognizing your escape sequence and not in your modification of putty.

Could you try with

(define-key input-decode-map "\e[1;2A" [S-up])

in your .emacs, relaunch emacs, press shift up and then CTRL-H L. Emacs should then show you how it interpreted your key press.
