PCI Modem Card User's Manual +DR Data Compression Report Value +DR=0 This command disables the compression report. +DR=1 This command enables the compression report. +DR Data Compression Reporting Intermediate Result Codes +DR: NONE +DR: V42B +DR: V42B RD +DR: V42B TD +DR: V44 +DR: V44 RD +DR: V44 TD Data compression is not in use. V.42 bis is in use in both directions. V. 42 bis is in use in the receive direction. V. 42 bis is in use in the transmit direction. V.44 is in use in both directions. V.44 is in use in the receive direction. V.44 is in use in the transmit direction. +DS=,,, -V. 4 2 bis Data Compression Use the +DS command to configure the V.42 bis data compression method used by the modem. The settings of this command overwrite the setting of a %C command. However, it can also be overwritten by %C command. The parameter sets which directions use the compression method. The soft modem use compression in one or both directions. Valid Values: 0 Modem negotiates no V.42 bis compression. 1 Modem negotiates transmit only V.42 bis compression. 2 Modem negotiates receive only V.42 bis decompression. 3 Modem accepts V.42 bis compression in both or either direction (default). The parameter tells the modem whether it should disconnect if V.42 negotiations fail. The soft modem AT command set does not support the disconnect feature when V.42 negotiation fails and the parameter is always set to 0. The and parameters specify the maximum number of dictionary entries and maximum string length for the modem to negotiate. Their default values are 4096 and 32, respectively. +DS44=,, , ,,,,,-V.44 Data Compression 48
