That may be the case, and it is indeed not a matter of low voltage (your
PCI SCSI card is low voltage, but don't unplug that with power on!), but
the chips that drive the ports generally handle hot-plugging just fine.
Of course, most of the data sheets from the manufacturer do not recommend
this practice, as something could possibly go wrong, and the standard
serial connector is not designed specifically for this behavior.
