Table 12-1: AT Commands in CDPD Mode (continued)

Command Description

<0xC0>

Escape sequence (SLIP service) (not preceded by AT).

+++While the modem is in data state in SLIP mode this SLIP embedded escape sequence can be

<0xC0> issued to bring the modem into the command state. The modem will remain in the on-line

condition.

	<0xC0> (decimal 192) is the SLIP frame character. There are no guard times associated with this
	escape sequence.
A/	Repeat Last Command (not preceded by AT).
	Re-executes the last AT command string entered.

AAnswer – Manual

Only valid in PAD mode (TCP or UDP) but not in SLIP mode.

When the modem is configured to allow server sessions (+WS212 is not 0) and auto-answer is disabled (S0=0), an incoming packet will cause the RING message to be issued and the RI signal to toggle. The host may then choose to accept the packet or ignore it. This command is used to open a server session and accept the packet.

Result Codes:
OK	Command was ignored – no pending packets.
CONNECT	normal response; the session is open.
ERROR	Not available with current settings, usually when auto-answer is enabled.
