Ask Larry Snyder about his experiences with Digiboard & Computone w/
Telebits!  They were not successful.  Last I heard on the net, Larry was
using a Comtrol Hostess DUMB board, which worked fine. 
What goes on now, Larry?

Also, I'm no expert on the anvil board, but doesn't it have a switch
for interrupts?  If it uses interrupts, then that may be the reason
why it doesn't run into any problems with Telebits.  

I like the Anvil stuff.  Their software Crocodile and Monitor is
pretty neat.  I haven't used it, but I've heard it is really good
for identifying system bottlenecks in Xenix.
