	Index), which is used for manual registration.

The D (Dial) command will also set this register if the N=n modifier is used to select the NEI for registration.

NOTE: If this register is modified while on-line, the currently active NEI is de-registered. If auto-registration (+WS173) is enabled then the new NEI is registered provided the index points to a valid NEI.

The modem supports up to four NEIs.

179 Registration Wait Status0, 1 0

This register only applies to SLIP and UDP service. It is ignored in TCP service.

Value Meaning

0ATD goes online immediately. (Default)

1ATD starts registration if needed and waits for registration to complete before returning the result (CONNECT).

197 Active NEI Index1 – 4 =+WS176

The modem supports up to four NEIs. This register defines the NEI that is the target of the following commands:

+WPDEREG (De-register) +WPREG (Register)

+WPNEI= (Write an NEI to the table) +WPNEI? (Read the active NEI)

Modifying this register does not affect the current registration status.

The default value on power-up sets this register equal to the contents of +WS176 (Auto-register NEI Index).

The D (Dial) command will also set this register if the N=n modifier is used to select the NEI for registration. This register will be set to the value of +WS176 (Auto-register NEI Index) prior to the setting forced by the Dial command.

198 Registration Wait Time1 – 255 30 seconds

Maximum amount of time for the +WPREG or ATD commands to wait for successful network registration before returning an error result.

This timer is related to registration with the network only. For TCP PAD connections, there is a separate timer in register S7 (TCP PAD Timeout) which must allow for BOTH this registration and the TCP connection handshake.
