Nejasnosti kolem PPP

[Zbynek Houska]

Vazeni uzivatele,

muze mi nekdo pomoct s odladenim ppp propojeni pomoci modemu?
Mam v konfiguraku toto:
default:
 set log Phase Chat LCP IPCP CCP tun command
 ident user-ppp VERSION (built COMPILATIONDATE)

 # Ensure that "device" references the correct serial port
 # for your modem. (cuaa0 = COM1, cuaa1 = COM2)
 #
 set device /dev/cuaa1

 set speed 115200
 set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \
           \"\" AT OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT"	

Po precteni man ppp je mi ledacos jasne... ale nejde mi do hlavy
nasledujici:
pokud spustim ppp jako root
dam set device /dev/cuaa1
a dale set speed 115200
a pak term coz mi umozni prime ovladani modemu
pak dam AT
dostanu OK
dam atdtmojecislo
a hlaska je BUSY

Nejsem si jist kde je chyba a nevim jak ppp mam rict aby necekal na ton.
Zde je jeste vypis z /var/log/ppp.log:
