AT Command Reference

data, Markov, or Loopback call is initiated. All other valid dial numbers, except dial numbers 1-99, initiate an asynchronous data call and return the result code of the Gateway IWF modem.

Dial numbers 1-99 correspond to phone book entries and are translated into dial numbers stored in the specified location. If the specified phone book location is unused, no call is attempted and NO DIALTONE is returned. If the phone book entry exists, a call is attempted using the dial number stored. Valid phone book entries include the Dial String Values listed below.

If ATD is entered by itself, then the modem attempts to call the previously called number (from the call history) if one exists.

Dial string modifiers and unrecognized characters included in this dial string are ignored as stated above.

Dial String Values

#777

Originate a packet data call.

#627568

Originate a Markov call.

#56672225 Originate a Loopback call.
