No, diald can be used with PPP or SLIP. Whether you actually use it or
not, SLIP support must be in your kernel.
There are a couple of reasons why you might want to use diald with
pppd.
* pppd must be started by hand before you start any network
activity. This is a pain (I think). diald sits in the background and
as soon as it detects outgoing traffic it dials your provider and
starts pppd. When you're done and there are no more packets on the
line diald drops the connection. This is very convenient if you want
to set up a cron job to retrieve email in the middle of the night, for
instance.
* if the call to your provider is long distance, or if your local call
is billed by the minute (likely if you're in Europe, unlikely if
you're in the US) you may find it convenient not to have the line up
all the time. diald can be set up to drop the line when there is no
traffic and bring it back up when you actually need it. There are some
problems here if you have dynamic IP assignment (see the FAQ).
