I have two Win9x systems connected to a passive KVM box. Whenever I
switch between them, the typematic settings are lost.
To work around this, I have a desktop shortcut which I access with
Ctrl_Alt_K and which executes the following command line:
C:\WINDOWS\COMMAND\MODE.COM con rate=32 delay=1
I don't know if a similar technique will work for Win2K and above.

I have a passive KVM box that connects two computers to an old
AT-style keyboard. AFAICS, switching between PCs is akin to
hotplugging the keyboard. I've done this hundreds of times without
incident. I would think that a properly designed KVM box should make
the power contacts before making the signal contacts, as is the case
with USB, but my box appears to have only a simple multipole rotary
switch.

ISTR AT style keyboards should be hot pluggable, in practice even
if not by design (similar to serial and parallel ports). It is
PS/2 ports that are potentially troublesome. Even then, many
mobo/keyboard combinations are perfectly happy with hot-plugging,
it is just there is no way of knowing if yours happens to be one
of them before trying it, by which time it may be too late.
Of course, I've no idea how this relates to the fact the two types
are electrically identical and you can easily adapt AT to PS/2 and
vice versa... the connections on an AT keyboard are standard 5-pin
DIN AFAIK, there's no differentiation in contact length. Maybe it
is simply standard practice that AT keyboard sockets have the
necessary protection in place.

Thanks, Franc, I'll give that a whirl the next time my cord becomes yanked.

The fact that the keyboard was not designed to be hot
pluggable was apparently the root cause of my problem. My
keyboard was destroyed. The PS2 port worked OK with another
keyboard, but, the optimal solution that I chose was to
switch to a hot pluggable USB keyboard. I have been using a
USB mouse for years.

No problems whatsoever.
I would not hesitate to do it on a brand new computer.

Yes. Well PS2 is for sure, I have done it on both my computers
with no problem.
Hard to see how any hard couldbe done

It ruined my keyboard to I switched to a USB keyboard.

??? how can you ruin a keybooard?
All you are doing is plugging it it, ie giving it power, which is
the same as you so when ou power your computer up.
I fail to see how any device can not be hot pluggable, to be honest.

More likely he meant it ruined the keyboard port on the PC.

Plug is half way in... the 5v and data lines have made contact, but not
ground. All power is shunted through the data leads - *POP*
