I have recently come into possession of an external serial modem, and 
have actually had some similar problems with it!  It turns out that I'm 
having a problem with an extension cable - I guess the signal must be 
getting too weak (I have only a shaky grasp of that kind of stuff).  I'm 
sorry to have wasted your time in this matter.  Of course, if you'd like 
me to continue with diagnostics to make the driver cope better with such 
situations, just let me know.
