\M Manual Transmit Control
Controls the recognition of data forwarding characters by the packet assembler while in online mode.
If enabled, the DART recognizes the reception of either of the two data forwarding characters from the
MAS as a condition to transmit any pending data. The data forwarding characters are defined in S-
Registers 51 (default is 13 <CR>) and 52 (default is 26 <SUB>). Refer to Data forwarding, p. 8-8, for
more information.
The AT\F command determines whether the forwarding characters are themselves included in the
packet. If manual transmit control is disabled, any forwarding characters are included in the packet
regardless of their disposition as defined by the AT\F command.
Format:
AT\M0 Disable recognition of data forwarding character (default)
AT\M1 Enable data forwarding character recognition, and use the conditional status of
the AT\F command
Result codes:
OK Valid argument
ERROR Invalid argument
\N Set Side Preference
Allows the MAS to set the modems side preference. The side preference identifies the CDPD Service
Provider and determines which group of cellular channels the modem searches for a useable CDPD
channel.
\N settings are not reset by ATZ, AT-R, or power cycling the modem
Format:
AT\N0 Home only mode. Alias for (and forces) \J1; does not specify a side setting.
Only allows use of channels that have the same LSAI (CDPD 1.0) or WASI
(CDPD1.1) as the active NEI
AT\N1 A side only
