Table F-1. Commands beginning with letters (cont.)
D (cont.) Format:
ATDPs s = destination address string plus optional modifiers
Sn Follows the T or the P Dial modifier, or replaces the string in the AT*P (PING)
command. It causes one of the modem’s stored destination addresses to be used
by the command involved. See the AT&Z command.
Format:
ATDTSn Select stored destination address <n> from the modem’s address list
where n = 0 to 9.
; The semi-colon (;) dial modifier follows the dial string and causes the DART to
return to command mode when connection setup is complete, rather than to enter
online mode.
Format:
ATDTs1; Return to command mode after connection is established (to
destination address string s1) instead of going online.
Result codes:
CONNECT Connection is established
NO CARRIER Connection is broken and extended result codes are selected, or command aborted
and extended result codes not selected (see ATX command).

attempted a data transmission after the RF link was lost.
For TCP or UDP, DTR was dropped to the local modem and &D2 had been
specified.
BUSY Connection is refused and extended result codes are selected (otherwise NO
CARRIER). For TCP, an invalid port was specified, the appropriate server is not
active, or the remote device is currently connected to another device.
NO ANSWER No response is received from the destination within the timeout period specified
by S-Register 7 and extended result codes are selected (otherwise NO
