Description

 

 

 

*DA

Default Telephone Number to Dial When DTR

 

 

108=On

 

 

 

0

=Off, no default

 

 

 

 

n

=Phonebook entry n, where n = 1 to 4, and a telephone

 

 

number is stored in n

 

 

 

*DB

Receive-Data Buffer Delay

 

0

=Disable buffer delay timer

 

 

 

 

1

=Enable. Buffer or S-Register 38. Starts the buffer delay

 

 

timer immediately upon detection of the disconnect

 

 

request. When the timer is operating, the modem

 

 

continues to process the transmit or receive buffers. The

 

 

modem disconnects when the buffers are empty or the

 

 

timer expires, whichever occurs first. Note: When the

 

 

modem is set for Direct mode, no data buffering occurs

 

 

and the disconnect is immediate.

 

 

 

 

2

=Buffer + S-Register 38. Prevents the timer from

 

 

starting until either the transmit or receive buffers have

 

 

emptied. The modem then disconnects. Once the timer

 

 

expires, when the modem is set to Direct mode, data is

 

 

not buffered and the timer starts immediately.

 

 

 

 

3

=S-Register 38. 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

 

0

=Disable.

 

 

Motorola recommends that you disable data

 

 

compression when you use remote configuration at rates

 

 

of 9600 BPS and below, because data compression may

 

 

produce fractured command responses that may be

 

 

difficult to interpret. Although the displayed responses

 

 

may be compromised, the configuration function works

 

 

properly with or without data compression.

 

 

 

The characters AT or at precede all commands except: +++, #####, and A/

 

 

 

Parameters and options shown shaded gray vary by country. For your country’s options,

refer to the 3460 Fast’R Reference Guide (T0022).

Default (pre-set) options are underlined.
