I hadn't heard of TIME /T. In NT it reports the time without
prompting for a new time. I don't see it documented anywhere. In
OS/2 the switch is /N. (You don't say what OS you're running.)

Yes, I get this in NT. Strange. Pushing the command into a BATch
file doesn't help. Yet DOS/NV/X /C TIME/? works (types the Help
screen before returning to Xy). (In OS/2, DOS/NV/X /C TIME/N works
as expected.)

Well, since TIME /T won't work with the DOS command, we'll need to
try something else. Recall that TIME with no argument reports the
current system time and then prompts for a new time; if you press
Enter, the prompt goes away. So let's try piping a carriage return
to a bare TIME command. Just might work.

Issue DECODE to decode the frame below. Copy it into U2.
Do NOT attempt to SAve or STore U2. Rather, issue LH, then
ABort the file. The command is NOW2.

I wonder if there's another, less complicated way to refresh the
system time. Is it possible that executing *any* command will wake
the system up? Let's try VER. The command is NOW3. Does
it work?
