I recommend you install diald to bring the line up and down for any user
according to demand. It's quite easy to install and uses your suseppp settings.
Most unwanted dialouts can be avoidd by using its config file to suppress any
netbios packets and by running DNS to remove the need to dial out to resolve IP
addresses.
In case you don't want to do this, and bearing in mind that I _am_ using pppd
via diald, my pppd looks like this:
-rwsr-xr-- 1 root dialout 83952 Aug 4 22:33 /usr/sbin/pppd
and my connect scripts like look like this:
-rwx------ 1 root root 3377 Dec 21 00:23 connect
-rwxr-xr-x 1 root root 487 Feb 19 1998 ppp-down
-rwxr-xr-x 1 root root 504 Dec 13 13:45 ppp-up
the shell script 'connect' takes the place of the ppd option "-chat
generic.chat" as it's got a few more bells and whistles (mainly to do with
putting more detailed information about failed connects into the log file).

The modem init string goes into your /etc/suseppp/whatever.chat at the very
beginning of the sequence (mine goes into the connect script above; one of the
advanteages of this script, which comes with the diald package but which _can_
be used just with naked pppd, is that it is much more structured and commented
and easy to understand where things go.
With regard to the values you should use: I am just using the factory-set
defaults.on my modem and these seem sensible enough. If you really want to tweak
it your best bet is to ask your ISP. If they are any good their technical
support department will have a list of the recommended setup strings for the
most popular branded modems. If you have an unbranded model look in that list
for modems which use the same chipset as yours.

MTU and MRU are set explicitly with the command-line options "mtu n" and "mru
n" for pppd. However I suggest you don't use these at all as ppps is I believe
supposed to autonegotiate these with the host to achieve the most efficient
value.
I'm using a 56K modem (external Hayes Accura speakerphone) with the V.90 BIOS
flashed into it and I am happy to report that when there isn't a host, routing
or bandwidth saturation problem between me and the source of the data I'm
downloading, I usually get 4 to 5 kilobytes per second and occasionally a little
more :-)
