Michael: I think you may have missed my early discussion of this 
problem, namely: "I use it to dial in to an old mainframe." My internet 
connection is via broadband so I do have all the latest patches 
installed. I appreciate your offer, tho. From my reading so far, UDEV is 
good, but still prone to some problems. I shall keep investigating, but 
at least for now, I can live with using ttyS14 when I have to refer to 
the modem -- there's still a chance that will stop working, I suppose, 
since I didn't try a reboot after I made that discovery. I'll have to 
wait till morning to see.
