8. Operating the MP215 via AT
Commands
The MP215 can be programmed to operate in one of its four modes, configured
via Register WS181, as follows:
1) CDPD Mode (WS181=0).
This mode provides regular CDPD service
2) CS-CDPD (WS181=1)
This mode provides CS-CDPD service, i.e. CDPD protocol over a conventional
AMPS call.
3) CS-CDPD, No Answer (WS181=5)
This mode provides CS-CDPD service but does not answer incoming calls (auto-
answer disabled).
4) AUTO (WS181=3)
In this mode the MP215 automatically switches between CDPD and CS-CDPD
modes depending on CDPD service availability. If both services are available it
will choose CDPD. While in CS-CDPD mode, and idle, it will periodically check
if CDPD service is available.
The AT command to control operational modes operates as follows:
AT+WS181= Set service preference
AT+WS181? Query service preference
Where n =
0 CDPD mode
1 CS-CDPD mode
3 AUTO mode
5 CS-CDPD, No-answer Mode
