Control Key triggers stream of characters
Posted on 2003-03-04
I have a Win98 PC with an interesting quirk.
Whenever I hit the (usually left) control key
as in Ctrl-X, Ctrl-C, Ctrl-V etc... characters
begin spewing from nowhere (as if typed at the
It is usually a single character repeated at
1-2 char/sec. If I actually physically type
characters on the keyboard, they appear interspersed
in the phantom stream.
Occasionally, while banging away on the keys,
the phantom stream switches to another character
(not obviously correlated to what I've been banging)
I've switched keyboards, sam ting.
I did an experiment using VNC over the network.
This phantom behaviour did not happen which
points in the general direction of hardware.
My guess is that it is a partially whacked out
keyboard controller, although that doesn't quite
smell right either. If the K/C was spontaneously autorepeating due to the occurence of Control=Key,
why would it still continue to correctly scan
other keycodes, and then return to both autorepeating,
and A/R the same character.
That sort of thing points to software in general,
and Windoze in particular...
Any ideas ?
