I think you want /dev/ttyS0, ttyS1, etc...
Also, I don't have a serial port on my laptop, but my USB to serial 
converter creates a device called /dev/ttyUSB0.  All these devices are 
present on my system (Ubuntu latest), but I have no idea how to check if 
they are valid.  Obviously, sending data to /dev/ttyS0 would do nothing 
on my laptop.

You could setup handshaking routines to check and see if there's a 
device that can respond on all of those devices.  Your device would have 
to be able to do hardware or software handshaking though.  Other than 
that, it's out of my league.
