Values returned by the respective modems for the registration result code differ in their
interpretation. The DART 200 showed the most recent carrier-returned result code. The
DART 300 shows a series of registration progress codes that will continually change as the
process proceeds. The registration result code is part of this progression, but its value is not
maintained in +WS201. To determine the actual result code, this register must be continually
monitored during the auto-registration process. Consult the AT command references for specifics.

Channel Acquisition Restrictions
The DART 300 supports only the SPNI matching restriction. This is automatic when there is an
entry in the SPNI list. The DART 200 supported SPNI, SPI, and WASI matching restrictions that
were controlled using \Jn, and a SPNI, SPI, or WASI list. The DART 300 does not support these
additional options.
