DART 200 CDPD Modem User’s Guide F DART AT Command Set

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.

Connection is established

Connection is broken and extended result codes are selected, or command aborted and extended result codes not selected (see ATX command).

For TCP, the other side of the connection executed an ATH, or the local modem 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.

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 response is received from the destination within the timeout period specified by S-Register 7 and extended result codes are selected (otherwise NO CARRIER). For TCP, auto answer was not enabled, or the destination modem was not reached because it was not registered, or had lost RF coverage.

The local modem is not registered with the network and extended result codes are selected (otherwise NO CARRIER)

Semicolon (;) dial modifier was used

Connection refused by the network; an extended reason code is written to registers S62 and S63.
