[luau] Tried a USB to serial adapter?

[Jeff Mings]

Hi Gang,

    This is a bit off-topic, but others may also find it interesting:
Has anyone tried one of the USB to serial port adapters?  I just 
purchased a Dell Poweredge server that has PCI 2.2 slots that are only 
keyed for 3.3v operation.  This means that the 4 serial port RocketPort 
card I have, which is keyed for 5v operation (ala PCI 2.1), won't fit 
into a slot.  I need 3 more serial ports and am considering trying one 
of the units that plug into a USB port and provide 4 serial ports, but I 
have never _really_ trusted USB for "important" things.   Any 
suggestions on these USB to serial adapters?

Thanks in advance,
-Jeff
