AT

Parameter &

 

Command

Option

Description

 

 

 

AT*DB3

=S38

This setting allows the timer to start immediately upon detection of a disconnect request. The

 

 

request continues to process either its transmit or receive buffers. The modem disconnects

 

 

when the timer expires, regardless of the buffer states. NOTE: In Direct mode, no data

 

 

buffering occurs. However, the modem delays a disconnect until the timer expires.

 

DC

Data Compression

AT*DC0

=Disable

Data compression is not attempted.

AT*DC1

=Enable

Data compression is attempted.

 

 

If the modem is using LAPM error correction, it uses V.42bis data compression when

 

 

DC=Enabled. NOTE: In an application with SDC enabled, LAPM error correction and

 

 

V.42bis data compression only are used.

 

 

If your modem is using MNP error correction, it attempts to negotiate V.42bis and MNP-5 data

 

 

compression with the remote modem.

 

 

Depending on which data compression type can be accommodated by the remote modem,

 

 

V.42bis or MNP-5 is used. Otherwise, no data compression is used.

 

 

 

 

Dial Wait

Dial Wait

AT*DD0

=2 sec

The modem waits 2 seconds for a dial tone.

AT*DD1

=3 sec

The modem waits 3 seconds for a dial tone.

 

 

AT*DD2

=4 sec

The modem waits 4 seconds for a dial tone.

AT*DD3

=6 sec

The modem waits 6 seconds for a dial tone.

AT*DD4

=12 sec

The modem waits 12 seconds for a dial tone.

AT*DD5

=15 sec

The modem waits15 seconds for a dial tone.

AT*DD6

=20 sec

The modem waits 20 seconds for a dial tone.

AT*DD7

=30 sec

The modem waits 30 seconds for a dial tone.

AT*DD8

=40 sec

The modem waits 40 seconds for a dial tone.

AT*DD9

=S7

Dial wait is determined by setting S-Register 7. (See the “S-Registers” section in Chapter 5).

The DTE port is configured for 2400 bps (this is the lowest rate available in SDC mode).

AT*DE6

=4800

The DTE port is configured for 4800 bps.

AT*DE7

=7200

The DTE port is configured for 7200 bps.

AT*DE8

=9600

The DTE port is configured for 9600 bps.

AT*DE9

=12.0

The DTE port is configured for 12,000 bps.

AT*DE10

=14.4

The DTE port is configured for 14,400 bps.

AT*DE11

=16.8

The DTE port is configured for 16,800 bps.

AT*DE12

=19.2

The DTE port is configured for 19,200 bps.

AT*DE13

=21.6

The DTE port is configured for 21,600 bps.

AT*DE14

=24.0

The DTE port is configured for 24,000 bps.

AT*DE25

=26.4

The DTE port is configured for 26,400 bps.

AT*DE26

=28.8

The DTE port is configured for 28,800 bps.

AT*DE15

=38.4

The DTE port is configured for 38,400 bps.
