I agree with Ron about using a LAN interface on the AS/400, but if you are simp
ly replacing
an existing point-to-point serial link with routers then you can still use the
serial
interfaces on the routers and use DLSW+ at the same time.
The main advantage to using the existing serial interface on the AS/400 is that
you don't
need to 'gen' a new configuration on the AS/400. I have done this for several
different
customers and can provide sample configurations.
