unit are communicating correctly (afterwards, this is no longer
necessary):

57600bps the baudrate of the emulator in order to use the voice call priority function in a
data connection.
2. Type
AT
, press
ENTER

is displayed on the screen then the PC and C
EL
L
INE
®
unit are
communicating correctly and the system is ready to send and receive data and SMS
messages.
3. In case any other message is displayed, you need to set the terminal to N,8,1 (C
EL
L
INE
®
is
programmed in autobauding).
NOTE: if the characters you type (e.g.
AT
