Out of curiosity, don't suppose you've seen the oops on IP22 that can sometimes 
be triggered by closing the serial client on another box?  Haven't investigated 
it too much, but I've seen the odd case on Indy and IP28 (which also uses the 
zilog driver) where shutting down my serial client or sometimes rebooting the 
system running the client oopses the driver.  I suspect some rogue data gets 
passed that zilog doesn't know how to handle properly.
