                                    ^^^^^^^^^^^ Presne to je to co chci.
Bohuzel se mi nedari ji nikde vydolovat. Mam nastavene debug u pppd, 
verbose u chatu a presto dostanuj jenom nasledujici:

Feb  4 08:39:00 twoflower pppd[340]: pppd 2.3.5 started by ...
..
Feb  4 08:39:03 twoflower chat[343]: send (ATDP22090911^M)
Feb  4 08:39:03 twoflower chat[343]: expect (CONNECT)
Feb  4 08:39:03 twoflower chat[343]: ^M
Feb  4 08:39:36 twoflower chat[343]: ATDP22090911^M^M
Feb  4 08:39:36 twoflower chat[343]: CONNECT
Feb  4 08:39:36 twoflower chat[343]:  -- got it 
Feb  4 08:39:36 twoflower chat[343]: send ()
Feb  4 08:39:36 twoflower chat[343]: timeout set to 30 seconds
Feb  4 08:39:36 twoflower chat[343]: expect (~)
Feb  4 08:39:36 twoflower chat[343]:  115200^M
Feb  4 08:39:39 twoflower chat[343]: ~
Feb  4 08:39:39 twoflower chat[343]:  -- got it 
Feb  4 08:39:39 twoflower chat[343]: send ()
Feb  4 08:39:39 twoflower pppd[340]: Serial connection established.
Feb  4 08:39:40 twoflower pppd[340]: Using interface ppp0
Feb  4 08:39:40 twoflower pppd[340]: Connect: ppp0 <--> /dev/ttyS0
..

Jedine co se dozvim je rychlost serioveho portu...
Modem mam nastaveny na X3 a podle manualu by mel po spojeni vracet CONNECT
XXXX, kde XXXX neni vysvetleno, ale predpokladam, ze je to prave ta rychlost.
Napadlo me, zda problem neni v tom, ze v podle chatscriptu ocekava CONNECT -
nelze mu nejak naznacit, ze za tim CONNECT ma nasledovat jeste cislo?
