will report “RING” to your terminal. External models will also make an audible ring notification.

Making V.110 Calls

Before the ATDIxxx command is given to place the call, you need to make sure that the TA is in asynchronous mode (AT&M0). Then use the following commands to configure V.110:

AT Command

Description

ATB10

User rate follows DTE speed (see note below).

ATB13

User rate = 2400bps.

ATB14

User rate = 4800bps.

ATB15

User rate = 9600bps.

ATB16

User rate = 14400bps.

ATB17

User rate = 19200bps.

ATB18

User rate = 38400bps.

ATB19

User rate = 57600bps (Japanese version only).

The highest Async V.110 user rate depends on bit 4 of S119 as follows:

S119.4=0

19200 bps.

S119.4=1

38400 bps for areas other than Japan (default).

S119.4=1

57600 bps for Japanese version.

If the DTE speed is higher than what has been set, the user rate on above table will be used.

Synchronous Connections (external)

Use the following commands to choose the data rate for synchronous operation :

ATB11

64000bps
