3.2 Description of messages
3.2.1 Commands with effect on messages
Insofar as the command ATQ1 is not active (messages off), the MicroLink
ISDN i will acknowledge input commands and provide messages—regarding
incoming calls or the establishment of a connection, for example.
With the default setting ATV1 , the MicroLink ISDN i returns messages in
plain text (followed by
M
and a line feed character). With the command
ATV0 , the messages are returned in short form as a digit (with a leading and
concluding
M
)
.
3.3 Caller ID of remote station
The ISDN supplies the caller ID of the incoming call, if this has not been sup-
pressed by the remote station. Register S153 can be used to set whether this
number should be displayed together with the RING and/or CONNECT mes-
sage.
Examples
RING;0241938800
CONNECT;0241938800
CONNECT 64000/ISDN/V120;0241938800
