AT Command Guide +DS - Data Compression +DS = [[,[,[,]]]] This parameter controls the manner of operation of the V.42 operation in the modem. It accepts 3 numeric sub-parameters: : Specifies the desired direction(s) of operation of the data compression function from the local PC point of view. : Specifies whether or not the local PC should continue to operate if the desired result is not obtained : Specifies the maximum number of dictionary entries, which should be negotiated : Specifies the maximum string length to be negotiated (V.42bis P2) 0 1 2 3 < compression_ negotiation > 0 1 < max_dict> < max_string> Description Negotiated - no compression (V.42bis P0=0) Transmit only Receive only Both directions, accept any direction (V.42bis P0=0) Description Do not disconnect if V.42bis is not negotiated by the remote modem as specified in Disconnect if V.42bis is not negotiated by the remote modem as specified in 2048 32 +DS? The modem shall send text to the local PC, consisting of: +DS: , , e.g. +DS: 3,0,2048,32 +DS=? +DS: (list of supported < direction > values, (list of supported < compression_negotiation > values), (list of supported values), (list of supported values) Modem responds with list(s) of supported values e.g. +DS: (0-3), (0-2), (2048), (32) +ER -Error Control Reporting +ER = This parameter controls whether or not the extended-format "+ER" intermediate result code is transmitted from the modem to the local PC: The +ER intermediate result code, if enabled, is issued after the modulation report (+MCR and +MRR) and before the Data Compression Report (+DR) +ER: NONE +ER: LAPM +ER: ALT Error control is not in use V.42 LAPM protocol is in use V.42 Alternative (MNP) protocol is in use 10 V90K56DOCATC11A
