Page 18: At Commands
6. AT Commands A – Answer The modem will go off-hook and attempt to answer an incoming call if correct conditions are met. Upon successful completion of answer handshake, the modem will go on-line in answer mode. The modem will enter the connect state after exchanging carrier with the remote modem. If no carrier is detected within a period specified in register S7, the modem hangs up. - Page 19 %C – Enable/Disable Data Compression Enables or disables data compression negotiation.The modem can only perform data compression on an error corrected link. Syntax: AT&%C<value> <value> = 0 Disables data compression. Resets S46 bit 1 1 Enables MNP 5 data compression negotiation. Resets S46 bit 1 2 Enables V.42 bis data compression.
