4 AT Commands, S-Registers, & Result Codes

 

Command: +DCS=x,y Select V.44 Data Compression

Values:

x = 0 or 1 (V.42bis)

 

y = 0, 1, or 2 (V.44)

Default:

1, 2

 

Description:

Selects V.42bis/V.44 data compression.

+DCS=0,0

V.42bis and V.44 data compression are both disabled.

+DCS=0,1

V.42bis is disabled; V.44 data compression is acceptable.

+DCS=0,2

V.42bis is disabled; V.44 only when connected to a V.92

 

server.

+DCS=1,0

V.42bis is acceptable; V.44 data compression is disabled.

+DCS=1,1

V.42bis is acceptable; V.44 data compression is acceptable.

+DCS=1,2

V.42bis is acceptable; V.44 only when connected to a V.92 server.

+DCS=?

Displays the allowed values.

+DCS?

Displays the current value.

Command: +DR=n

V.44 Data Compression Reporting

Values:

n = 0 or 1

Default:

0

 

Description:

Enables or disables the V.44 data compression report. If the

 

compression report is enabled, the +DR:<type> intermediate

 

result code reports the current DCE-DCE data compression type.

 

It is issued after the Error Control Report (+ER) and before the

 

final result code (e.g., CONNECT). The intermediate result

 

code descriptions are shown after the command descriptions.

+DR=0

Disables the V.44 compression report.

+DR=1

Enables the V.44 compression report.

+DR=?

Displays the allowed values.

+DR?

Displays the current value.

+DR: NONE

Data compression not in use.

+DR: V42B V.42bis is in use in both directions.

+DR: V44

V.44 is in use in both directions.

Command: +DS44=n V.44 Data Compression

Values:

See description

Default:

See description

Description:

Controls the V.44 data compression function.

 

The command syntax is +DS44=[direction][,[0][,[0]

 

[,[max_codewords_tx][,[max_codewords_rx][,[max_string_tx]

 

[,[max_string_rx][,[max_history_tx][,[max_history_rx]]]]]]]]]<CR>

Subparameters that are not entered retain their current value. Commas separate optional subparameters, and must be inserted to skip a subparameter. Example: +DS44=,,,2048,2048<CR> changes the maximum number of code words in both direc- tions, and keeps all other settings at their current values.

+DS44=? Reports supported options in the format (list of supported direc- tion values), (0), (0), (list of supported max_codewords_tx val- ues), (list of supported max_codewords_rx values), (list of sup- ported max_string_tx values), (list of supported max_string_rx val- ues), (list of supported max_history_tx values), (list of supported max_history_rx values). Example: +DS44: (3, 0), (0), (0), (256- 2048), (256-2048),(31-255),(31-255),(512-11008),(512-11008).
