Difference Summary

3.2.Operation

3.2.1.Monitoring Network Connection

Both modems provide mechanisms to monitor the CDPD network connection although the methods to access this information differ.

1Values 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.

3.2.2.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.
