Yeah, I guessed as much.  I have seen one of those buggers... Too bad
it is 100 miles away and probably not even there...  I think they sold
them at Radio Shack, though.
PS: It probably won't help, but you can set a read to be non-blocking.
PPS: Cat works, but lacks the subtelties of ioctls -- ie, it becomes
     difficult to set the speed and other options.
