  Oh, blimey, didn't you see that!  Igor already answered it: the answer is
yes, the /dev directory is a bit funny because it's virtual, but you can see
it by entering "ls -la /dev/ttyS0" explicitly; the mapping is that windows COM
port N is dev/ttyS N minus one; and although "ls -la /dev/ttyS.." will work
for more serial ports than there actually are, you'll get ENOENT if you try
and use one that doesn't correspond to an actual windows COMx device.  See
