Nansi.sys, available in source via anonymous ftp from the Info-PC digests
at c.isi.edu, implements a very complete set of Ansi commands, including
the ones you mention.  It is a superset of and replacement for IBM's 
incomplete implementation, Ansi.sys.  Nansi.sys is often included with
packages like PC-Hace and MicroEmacs that require it's full Ansi implementation
to correctly function.

As to making the PC's keyboard behave like a real vt100, that is a different
problem, and the proper concern of terminal emulators, not device drivers.
In the interest of refraining from a religious debate, I will simply 
mention that PC/Intercom by Mark of the Unicorn has very good emulation,
CrossTalk is almost as good, and the new MS-Kermit ver 2.29 is also
good.  MS-Kermit has to be the emulator of choice if true color emulation
is desired; PC/Intercom treats all colors as simply reverse video, and
CrossTalk won't even do that!
