 Just a bit more details on the problem...
 
 I just measured the serial port voltages when I have a com port open in =
 a terminal application (kermit, opening /dev/cuauX device) and there are =
 no voltage changes when hitting keys.
 
 Further, when measuring com1, which is setup as serial console in =
 /etc/ttys, there are expected voltage changes happening during boot, or =
 when kernel messages get generated on console (eg, unplugging a usb =
 device, etc), but there are no changes what so ever at other times (when =
 Login: is supposed to show up, keys are hit, etc).
