Locking a terminal is an interesting question which has bugged me too.
Ctrl-D is not a signal, it just closes stdin. It's also a function of the terminal, hence controlled by stty. I'm not sure it even can be disabled. Not even 'su -' can ignore ctrl-D and it's the one thing that can ignore everything else... IGNOREEOF=-1 will stop the terminal from quitting from it at least.
If you're changing the terminal settings it'd be wise to save/restore them since they're global to the terminal.
-----Post Update-----
Setting the EOF char to something impossible may work. 'stty eof 255'

term::ansi::ctrl::unix(3tcl) Terminal control term::ansi::ctrl::unix(3tcl)__________________________________________________________________________________________________________________________________________________NAME
term::ansi::ctrl::unix - Control operations and queries
SYNOPSIS
package require Tcl 8.4
package require term::ansi::ctrl::unix ?0.1.1?
::term::ansi::ctrl::unix::import ?ns? ?arg...?
::term::ansi::ctrl::unix::raw
::term::ansi::ctrl::unix::raw
::term::ansi::ctrl::unix::columns
::term::ansi::ctrl::unix::rows
_________________________________________________________________DESCRIPTION
WARNING: This package is unix-specific and depends on the availability of two unix system commands for terminal control, i.e. stty and
tput, both of which have to be found in the $PATH. If any of these two commands is missing the loading of the package will fail.
The package provides commands to switch the standard input of the current process between raw and cooked input modes, and to query the size
of terminals, i.e. the available number of columns and lines.
API
INTROSPECTION
::term::ansi::ctrl::unix::import ?ns? ?arg...?
This command imports some or all attribute commands into the namespace ns. This is by default the namespace ctrl. Note that this is
relative namespace name, placing the imported command into a child of the current namespace. By default all commands are imported,
this can howver be restricted by listing the names of the wanted commands after the namespace argument.
OPERATIONS
::term::ansi::ctrl::unix::raw
This command switches the standard input of the current process to raw input mode. This means that from then on all characters typed
by the user are immediately reported to the application instead of waiting in the OS buffer until the Enter/Return key is received.
::term::ansi::ctrl::unix::raw
This command switches the standard input of the current process to cooked input mode. This means that from then on all characters
typed by the user are kept in OS buffers for editing until the Enter/Return key is received.
::term::ansi::ctrl::unix::columns
This command queries the terminal connected to the standard input for the number of columns available for display.
::term::ansi::ctrl::unix::rows
This command queries the terminal connected to the standard input for the number of rows (aka lines) available for display.
