attempt if a character is entered. This item is only meaningful with the
acknowledged mode of operation.
&N0 Ignore characters entered while attempting to make a connection.
&N1
 If a key is hit while attempting to connect, abort the connection attempt and
return to command mode.
AT&P Protocol Routing Paths – Up to 100 paths can be stored. Routing paths are used
in conjunction with host protocol specific routing, so that device addresses may
be extracted from the data frame and used to direct the message. Each path
consists of a destination address extracted from the protocol frame, a radio
destination address and up to 6 store and forward addresses.
Format:
1. “AT&Pxx= a[-a]:{n,}f”.
“xx” = 0 to 99. “a” = 0 to 65535 (depending on protocol). “n” = 0 to 127,
“f” = 0 to 255. This indicates the path to send the message. “a” is the
protocol address to match. (“a-a” indicates a range of addresses) “n”
indicates a repeater address in the radio network, and “f” indicates the
final address (0-127 indicates RS232 port, 128-255 indicates RS485 port)
2. “AT&Px=” “x” = 0 to 99. Clear path number “x”
3. “AT&Px?”. “x” = 0 to 99. Display setting for Path “x”
4. “AT&P?” or “AT&P” – Display all configured paths
5. “AT&P=” Clear all paths
These paths may apply to either the RS-232 port or the RS-485 port depending
on the modem’s operating mode
AT&R Repeater Functionality– Enable or disable repeating of messages to the wildcard
addresses 0 and 128, and enable or disable sending messages to serial port . (Also
see AT&H command).
&R0
 Don’t repeat messages to the “Wildcard” address, and don’t copy wildcard
messages out the local serial port..
&R1
Repeat Messages when the wildcard address is the next un-visited
Store&Forward address in the message, and message has done the number of
hops specified by the AT&H setting.
&R2
Send a copy of the message out the local serial port when the wildcard address is
the next un-visited address in the message, and message has done the number of
hops specified by the AT&H setting.
&R3
Do both Actions – Forward the message and send a copy of the message out the
local port – when the next store & Forward address is the wildcard address and
the message has done the number of hops specified in the AT&H setting.
AT&T Self Tests. Allows in-field diagnostics, and factory testing. Tests time out after
the period configured in S-Register S8 (if not zero).
