dz11 / eia h3006 information wanted

[Karl Nyberg]

I just received a dz11 board and h3006 eia interface panel (8
lines), but no documentation (for the price I didn't pay...).
After much testing and gnashing of teeth, I have the address 
and vector information set up so that the operating system can 
find the board.  Now, however, I've got 10 dip switches that 
have to be set for each of the lines.  Can anybody tell me how 
to set those for a) incoming modem connections, b) outgoing modem 
connections (using a VenTel), and c) regular terminal connections?  
I think I have done the proper MAKEDEV as well as updated /etc/ttys 
correctly.  Thanks.
