USB KVM switch that does not eat control characters

USB KVM switch that does not eat control characters

[Jeffrey C Honig]

I've been using a Belkin 2-port USB KVM switch for a while to switch
between a couple PCs.  I'm actually only using the keyboard/mouse
switching and using x2vnc to control two monitors.

I have serveral problems with this KVM switch that impact emacs most
of all, so I thought I would ask here first.

First, the meta keys (ctl, alt) appear to time out, if I hold down the
control key I am eventually typing normal characters.  Also, F7 is
interpreted as a hot key and not passed.

These problems were apparently fixed by a firmware upgrade.  The
problem is that after this firmware upgrade, two presses on the
control key within two seconds are now the hot key sequence.  Even if
I hit other characters than control in between (so ^X4^U will be
interpreted as a hot key sequence).

Anyone have experience with a USB KVM that doesn't interfere with
control characters?

Thanks.
