You might have an easier time with SCP than SFTP.
SCP uses SSH under the covers, which in turn can use public/private
keys instead of passwords. The pass phrase for the secret key is
processed on the *client* side, so there is no need to convey it in
the transaction. (And there are agents and other means of handling
the pass phrase, which I omit to keep this short.)
So the equivalent operation with SCP (no scripting required) is
something like ...
scp zvm.note userid@100.1000.100.100:/users/nyse/zvm.note
EXPECT is a terrific tool, but the burden it carries (simulating the
user at a keyboard) can lead to the idle waiting that you see.
