AT Command Reference

Table 12-3: AT [+] Commands in CDPD Mode (continued)

Command Description

+WVRESET Soft Modem Reset

Resets the modem to power-up condition. This command will gracefully de-register the modem prior to resetting but will not gracefully close a TCP session.

12.3. CDPD Status Registers

All status registers (both S and +WS) for CDPD mode are independent of registers in other modes with the exception of +WS46 (Modem Operating Mode).

12.3.1.S-Registers in CDPD Mode

Table 12-4: S-Registers in CDPD Mode

Register	Description	Range	Default Units
0	Auto-answer	0 – 255	1

Auto-answer is not available in SLIP service (+WS45=3). The modem must be in PAD service (UDP or TCP) in order to change this register setting. The value of this register is ignored if server sessions are disabled (+WS212=0) or the modem is in SLIP service.

The modem must be registered on the network in order for this register setting to have meaning. If there is an active session, attempts to change this register will fail with the ERROR result code returned.

If auto-answer is enabled when a packet arrives on the port specified in +WS212 (Listening Port), and is accepted under Friends Only, the modem will issue “RING”, toggle the RI signal once, and issue “CONNECT <IP>” where <IP> is the address of the caller. The modem will then enter data state with a server session open.

If server sessions are enabled (+WS212 > 0) and auto-answer is disabled, an arriving packet (from an accepted friend) will trigger the RING message and the RI signal will toggle three times, but a session will not be opened unless manually answered with the A command.

Value	Meaning
0	Disable auto-answer.
>0	Enable auto-answer. (Default is 1)

2Escape Character0 – 255 43 <+> ASCII

This specifies the ASCII decimal code of the time dependent escape sequence (TDES) character. The standard escape character is the plus sign (+).

A value of 128 – 255 disables the time dependent escape sequence capability.
