I'm using putty's plink command to login to serial console, when press up arrow key, 0x1b 0x5b 0x41 is expected to set to MCU and I can use the shell history. But it doesn't work, it's work in putty GUI.

I tried windows' cmd terminal, conEmu terminal and git bash terminal, all of them doesn't work.

  • Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. – Community Nov 26 '21 at 08:56
  • Are you connecting from Windows to Linux?

  • I'm connecting to an RTOS. Using putty GUI is ok, but putty's command line tool plink doesn't. – Divlaker Nov 27 '21 at 01:24

From plink documentation:

Plink is probably not what you want if you want to run an interactive session in a console window.

You probably need PuTTY, which is a real terminal capable of handling non-ASCII key strokes.

If you want to skip PuTTY's configuration GUI and launch it directly as a serial terminal from command line try something like:

C:\Putty\putty.exe -serial COM4 -sercfg 115200,8,n,1,X
