Register (Manual) 

Registers the NEI entry indexed by +WS197 (Active NEI Index) with the network.  The 
command waits for the registration process to complete, or a timeout based on 
+WS198 (Registration Wait Time), and prints the registration result code. 

Register +WS201 (Registration Result Code) can also be read to determine the registration 
process status. 

If a different NEI is already registered, it is de-registered first.  If the current NEI is already 
registered, the registration result code is returned without re-registration. 

Sets +WS176 (Auto-register NEI Index) = +WS197 (Active NEI Index).  +WS176 is stored in 
non-volatile RAM.  +WS197 is set equal to +WS176 on reset or power-up.

Service Provider Network ID Table Write. 

The modem can be restricted to only accept CDPD service from networks whose network ID is 
configured in the SPNI table.  This command accepts up to 10 SPNI values.  SPNI values are 
entered in decimal, separated by commas.  This feature is disabled if the table is empty. 

Entering the command without parameters empties the SPNI table. 

NOTE:  Parameters will replace any previous table in its entirety.  New entries are not appended.  
The entire table must be entered, omitting deletions and adding new values. 

Service Provider Network ID Table Read 

Returns the SPNI table.  The modem can be restricted to accept CDPD service only from networks 
whose network ID is configured in the SPNI table.  This feature is disabled if the table is empty.
