btModem User’s Manual AT Command Set
Section 1. Data Mode Command A/ Executes Last Command When modem receives this command, modem executes the last command string entered. Do not conclude it by pressing “Enter”. A Answer Command This command instructs the modem to go off-hook and answer an incoming call. Bn Communication Standard Setting This command determines ITU-T vs. Bell standard. B0* Selects ITU-T V.22 mode when the modem is at 1200 bits/s. (Default) B1 Selects Bell 212A when the modem is at 1200 bits/s.
On Return Online to Data Mode O0* Exit online command mode and return to data mode (see AT Escape Sequence, +++AT). (Default) O1 This command issues a retrain before returning to online data mode. O2 This command issues a rate re-negotiation before returning to online data mode. Result Codes: OK n = 0, 1, 2 ERROR Otherwise P Select Pulse Dialing This command configures the modem for pulse (non-touch-tone) dialing.
Zn Recall Stored Profile This command instructs the modem chip set to go on-hook and restore the profile saved by the last &W command. Z0* Reset modem and retrieve active configuration profit from stored profit 0. (Default) Z1 Reset modem and retrieve active configuration profit from stored profit 1.
&Yn Select Stored Profile for Power On or Reset This command does not change the behavior of the modem but is included for compatibility with applications that issue the &Y0 command &Y0* Select stored profile 0. (Default) &Y1 Select stored profile 1. Result Codes: OK n = 0,1 ERROR Otherwise &Zn = x Store Telephone Number This command is used to store up to three dialing strings in the modem nonvolatile memory for later dialing.
*NCnn Country select This command provides customers chose the country for phone line regulation.
Section 2. Result Code Section 3.
S6 Wait Before Dialing This register sets the length of time, in seconds, that the modem must wait (pause) after going off-hook before dialing the first digit. The modem always pauses for a minimum of two seconds, even if the value of S6 is less than two seconds. Waiting for dial tone call progress features (W dial modifier in the dial string) will override the value in register S6. This operation, however, may be affected by some ATX options according to country restrictions.
S22 Bit mapped Register Bit-mapped register S22 lets you control internal speaker and the modem responses.
