MP. 8 ] parm__dp_cmn_binary_en Binary Diagnostic Mode

This parameter invokes a binary diagnostic mode when a direct mode connection has been established. The bit stream, as seen on the line interface, is placed into the DTE buffer, one octet at a time. The DTE interface rate must be faster than the line rate (10/8ths faster when the DTE interface is set to 8N1) in order for the buffer not to overflow. This mode is useful for diagnostics.


Range: TRUE, FALSE
Default: FALSE

MP. 9 ] parm__dp_cmn_hdlc_en HDLC Diagnostic Mode

This parameter invokes an HDLC diagnostic mode when a direct mode connection has been established. In the Rx data path, both bytes of the data unit are released to the DTE (most significant byte first). In the transmit data path, an HDLC frame is generated with all data up to a DLE ETC from the DTE. This mode is useful for diagnostics.


Range: TRUE, FALSE
Default: FALSE

MP.10 ] parm__dp_lapm_to_sync Sync Mode

This parameter invokes a synchronous mode of the Modem when a non-LAPM HDLC frame is detected.


Range: TRUE, FALSE
Default: FALSE

MP.11 ] parm__dp_mnp_block_mode_en MNP Block Mode

This parameter specifies the selection between block and stream modes of operation during the MNP error correction data protocol.


Range: TRUE, FALSE
Default: FALSE

MP.12 ] parm__dp_mnp_data_compression_select MNP Compression Mode

This parameter specifies the particular compression that MNP should use. This parameter is not used to specify that compression must be used, rather it only specifies the type of compression that can be used. MNP10 requires the use of BTLZ if available and compression is enabled; this parameter is therefore ignored for MNP10.


Default: DP_MNP_COMPRESSION__BTLZ_REQUESTED

MP.13 ] parm__dp_mnp_header_optimize_en MNP Phase Optimization

This parameter is used to enable data phase optimization, the use of optimized header fields in MNP data and acknowledge frames. This reduces the amount of information that is transmitted between the two modems during an MNP connection and therefore slightly increases the potential throughput.


Range: TRUE, FALSE
Default: TRUE

MP.14 ] parm__dp_mnp_max_data_size MNP Compression Mode

This parameter is used to restrict the maximum size of transmitted data packets. This software however ensures that the maximum data size does not exceed the negotiated maximum.

Range: 64-256, normally in multiples of 64
Default: 256

MP.15 ] parm__dp_mnp_service_class MNP Service Class

This parameter is used to select the MNP service class. Service class 1 is a half duplex communications protocol and is not implemented. Service class 2 and 3 are full duplex protocols. Service class 2 uses asynchronous character based packets, service class 3 uses HDLC synchronous packets after the LR packets.


Service class 4 introduced optional features that are compatible with the basic aforementioned packet types. These features are enabled by other MNP protocol related parameters.
Default: DP_MNP_CLASS__FULL_SYNC

MP.16 ] parm__dp_disconnect_mgmnt_mode Disconnect Management Mode

This controls the delivery of pending or accumulated data upon the receipt of a disconnect request.


In this context, the term "abandon" refers to the immediate discard of all data. The term "forever" refers to forever attempting to deliver the data, prematurely terminating only upon a disconnect request from the controller other than the one that initiated the disconnect. (The two controllers refer to the remote modem and the local host controller.) The term "timed" refers to attempting to deliver data as specified for the "forever" case, except abandoning when the disconnect management timer expires.
