Zhichao:

  One clarification. What terminal type will be introduced? Xterm, VT400 and Linux?

Thanks

Subject: [edk2-rfc] UEFI terminal console keyboard type extend for Putty

Hi everyone,

Putty is a popular terminal console software in windows and it support various types of terminal keyboard type. I would like to add most of the type support. Here is the key map info. Hope to get comments. Here is the type and mapping table:

Putty function key map:

  +=========+======+===========+=============+=============+=============+

For Xterm R6 F1 and F2, it is descripted as ESC+O+P and ESC+O+Q, but it doesn’t work on UEFI shell. Same with the SCO mode. So I would ignore the unworkable key map.
