A2.2.5.2 +DR
=[<value>]
- Data Compression Reporting
This extended-format numeric parameter controls whether or not the extended-format “+DR: “ intermediate result
code is transmitted from the modem to the DTE.
Defined Values
<value> decimal number corresponding to the selected option:
0
= Data compression reporting disabled (no +DR result code transmitted).
1
= Data compression reporting enabled (+DR result code transmitted). (Default.)
Reporting Current or Selected Values
Command: +DR?
Response: +DR: <current value>
Reporting Supported Range of Parameter Values
Command: +DR=?
Response: +DR: (<value> range)
A2.2.5.3 %C
[<value>]
- Enable/Disable Data Compression
Enables or disables data compression negotiation. The modem can only perform data compression on an error
corrected link.
Defined Values
<value> A decimal number corresponding to the selected option:
0
Disables data compression.
1
Enables both V.42 bis and MNP 5 data compression.
2
Enables both V.42 bis and MNP 5 data compression.
3
Enables both V.42 bis and MNP 5 data compression. (Default.)
A2.2.5.4 N
[<mode>]
- Automode Enable
This command is included for compatibility only and has no effect other than returning a result code. The only
valid values are 0-1.
A2.2.6 Synchronous Access Mode Commands
A2.2.6.1 +ESA
=[<trans_idle>[,<framed_idle> [,<framed_un_ov> [,<hd_auto>[,<crc_type> [,<nrzi_en>[,<syn1>
[,<syn2> ]]]]]]]]
- Configure Synchronous Access Mode
This extended-format compound parameter controls the manner of operation of the Synchronous Access Mode
in the modem. Enabling Synchronous Access Mode enables the use of the 8-bit command characters defined in Table
9/V.80 of the Draft ITU-T Recommendation V.80 (DATA COMMUNICATION OVER THE TELEPHONE NETWORK; In-
Band modem Control and Synchronous Data Modes for Asynchronous DTE).
Defined Values
<trans_idle> Decimal number which specifies the bit sequence transmitted by the modem when a transmit data
buffer underrun condition occurs, while operating in Transparent sub-Mode. The options are:
0
In Transparent sub-Mode, modem transmits 8-bit SYN sequence on idle. Modem receiver
does not hunt for synchronization sequence (default and fixed).
