That should work just well. Most people do not use CNTRL-C to kill
this process. Usually it is started to run in the background and then
killed using the command you just stated.
pppd has a lot of options to control on-demand/disconnect operations.
The OP should really "man pppd" and look at the demand, holdoff, idle
and [no]persist options. These can be placed in "/etc/ppp/options"
(globally applied) or "~/.ppprc" (per-user).
