Check with a simple 'cat' command outside screen whether the remote is
getting nothing at all, or something wierd.  At any rate, putty's
config somewhere has a "terminal emulation" setting, which includes
how settings for how it sends keystrokes like this.  $TERM
is usually propagated by ssh, so putty is likely to be setting it.
Choosing something else (eg. xterm instead of vt102) might be the way
to go.

ctrl+` is particularly wierd because it's ^@ (ie. \0, 0x0, NUL) in my
xterms, at least.  ctrl+space does the same.
