We configure a cisco 819 as follow:
*************
chat-script hspa "" "AT!SCACT=1,1" TIMEOUT 60 "OK"
interface Cellular0
ip address negotiated
encapsulation slip
dialer in-band
dialer idle-timeout 0
dialer string hspa
dialer-group 1
async mode interactive
line 3
script dialer hspa
modem InOut
no exec
rxspeed 21600000
txspeed 5760000
**************
the following output show that the chat-script is correctly working
