tput will use the terminfo database associated with the environment you are in (echo $TERM). Your "physical" terminal might be a different type. Just because a "physical" (could be a terminal emulator, like PuTTY) says it is using a particular terminal type doesn't mean there is a proper match with the TERM/terminfo being used.

The terminfo database is there so that you can handle whatever terminal might be used. The ability to directly query the "physical" terminal and therefore set TERM correctly isn't guaranteed.

Look under ther Terminal settings of PuTTY to adjust. If memory serves me correct, the SCO entry handles the most (ctrl, alt, shift combos)... BUT I don't believe the terminfo db for any of the SCO ansi terms in Linux is quite up to snuff... but you could create one (I know I have in the past).

ttytype

TTYTYPE(5)						     Linux Programmer's Manual							TTYTYPE(5)

NAME

       ttytype - terminal device to default terminal type mapping

DESCRIPTION

       The  /etc/ttytype  file	associates termcap(5)/terminfo(5) terminal type names with tty lines.  Each line consists of a terminal type, fol-
       lowed by whitespace, followed by a tty name (a device name without the /dev/) prefix.

       This association is used by the program tset(1) to set the environment variable TERM to the default terminal name for  the  user's  current
       tty.

       This  facility was designed for a traditional time-sharing environment featuring character-cell terminals hardwired to a UNIX minicomputer.
       It is little used on modern workstation and personal UNIX systems.

FILES

       /etc/ttytype
	      the tty definitions file.

EXAMPLE

       A typical /etc/ttytype is:

	      con80x25 tty1
	      vt320 ttys0

SEE ALSO
