alternative commands or registers where equivalents exist.
Table 4-3: AT [\] Commands
Command DART 200 DART 300 Equivalent
\F
Character Data Forwarding Operation
The DART 200 supports two forwarding
characters, indicated in S51 and S52.
The \F command determines whether any of
the data forwarding characters specified in S51
and S52 are included in the packet transmitted
to the remote data service.
PAD Forwarding Character Feature Mask
The DART 300 supports only one forwarding
character, indicated in +WS64.
+WS63 sets the handling of the primary
forwarding character.
\F0 = +WS63=1
\F1-3 = +WS63=3
\J
Restrict Channel Selection
Allows channel acquisition to be restricted
based on the carrier settings for SPNI, SPI,
and/or WASI. See the DART 200 User Guide
for details..
Service Provider Network ID Table Write.
Restricts channel acquisition based on carrier’s
SPNI.
\J0 = +WPSPNI=<enter>
\J1 = not supported
\J2 = +WPSPNI=<list>
\J3-7 = not supported
\M
Manual Transmit Control
Enables or disables packet forwarding based
on a forwarding character. If enabled then \F
controls additional behaviour.
PAD Forwarding Character Feature Mask
\M0 = +WS63=0
\M1 = +WS63=1 or 2 (see \F above)
\N
Side Preference
Allows setting of channel side preference
including setting of home only.
Channel Side A/B Preference
Does not directly support “home only” (\N0);
use +WPSPNI to restrict to home provider in
conjunction with side preference.
\N1 = +WS174=3 (A only)
\N2 = +WS174=4 (B only)
\N3 = +WS174=1 (A Preferred)
\N4 = +WS174=2 (B Preferred)
\O
