If the problem persists after checking the above possibilities, try power
cycling the modem. If that fails to help, contact your modem supplier for
assistance.
To determine if you have a channel restriction problem check the setting
of the \J parameter with an AT&V. If it is \J0 then the DART 200 has no
channel restrictions, so this can be eliminated as a possible source of the
problem. If \J has any other value then bypass the problem by entering
the AT\J0 command followed by an AT&W.
The S-Registers of interest in the AT&V+ output are summarized in
Table 2-1. The remainder of S-Registers are described in Appendix E,
S-Registers.
Table 2-1. S-Registers above 100
S100 The channel currently being reported (may not be acquired)
S101 Will be 1 if a channel has been acquired
S102 RSSI for the channel being reported
S103 Output power (0 to 7 with 0 being highest and 7 lowest)
S104 MDBS power product (a request for a specific power output)
S105 Current BLER (receive block error rate - %)
S106 Current SER (symbol error rate - %)
S107 Current LSAI (CDPD V1.0), or WASI (CDPD V1.1)
S108 Current SPNI (service provider network identifier)
S109 Current CSI (channel stream identifier)
S110 Current LCI (local cell identifier)
S111 Current Area/Cell color code
S112 Current TX BLER (transmit block error rate - %)
S113 Current SIE (symbols in error)
S114 Current SPI (Service Provider ID) (CDPD V1.1)
XID RSSI threshold, time (CDPD V1.0)
* threshold is dBw above -143 (in this case -125);
* time (in 1/10 sec) is how long RSSI can be below threshold before a
channel hop must be taken (5 seconds in this case)
S115 Not Used (CDPD V1.1)
XID BLER threshold, time (CDPD V1.0)
* Block error rate threshold (1/n) in % (10% in this case)
* time (in 1/10 sec) is how long BLER can be above threshold before
a channel hop must be taken (1 second in this case)
S116 Not Used (CDPD V1.1)
XID SER threshold, time (CDPD V1.0)
* Symbol error rate threshold (1/n) in % (10% in this case)
* time (in 1/10 sec) is how long RSSI can be below threshold before a
channel hop must be taken (5 seconds in this case)
