18AT dialingAT dialingAT dialing is similar to the methods used to make data calls with a HayesSmartmodem. Some AT commands do not apply to the MCA, and are notsupported.Most AT commands begin with the letters AT (not case sensitive). These two lettersare followed by a one- or two-character command (sometimes followed byadditional parameters) and a carriage return. Each command line is limited to amaximum of 40 characters (not including the AT and spaces).You will not hear any tones when using AT dialing with the MCA.Note: Remember that all of these commands (except A/ and the escape code) arefollowed by a carriage return).If you don not include a numerical parameter with a command, the MCA assumesthe parameter to be zero (0).A/ (repeat last command)This sequence repeats the last command you entered. It is not preceded by AT andnot followed by carriage return.ATA (answer)This answers an incoming data call when the MCA is set for manual answer(S-register 0 = 0).ATCn (carrier detect enable/disable, where n = 0, 1)Carrier detect is enabled when n = 1, disabled when n = 0. When enabled, thecarrier detect lead will be off until a data call has been established.ATDxxxx (dial, where x = 0–9)This performs a manual data call. The digits, xxxx, represent the phone number ofthe far end data device.ATEn (echo, where n = 0, 1)Commands do not echo back to your terminal when n = 0. Meaning, you do notsee your commands, only their result. Commands will echo when n = 1.
