The Home of Packet Radio
Defines the maximum no-activity period (measured in 10-millisecond increments) permitted by the link layer 
before it issues a poll to make sure the link is still intact. This timeout is also used to break link-layer choke 
deadlocks. NOTE: This parameter is the same as CHECK, and can be defaulted to 0 as a means of reducing node 
QRM. 
Parameter 23 AX.25 digipeating (1=enabled, 0=disabled) (default=0, minimum=0, maximum=1) 
Defines whether or not the node will perform AX.25 digipeating. The default value of 1 causes digipeating to be 
enabled. 
Parameter 24 Validate callsigns (1=enabled, 0=disabled) (default=1, minimum=0, maximum=1) 
Defines whether or not the node will perform validation checks on amateur callsigns. The default value of 1 causes 
callsign validation to be enabled. 
NOTE; If callsign validation is turned OFF (0), users will experience long delays if they request connects to 
inactive nodes before getting back a FAILURE WITH, response. 
Parameter 25 Station ID beacons (2=on, 1=conditional, 0=off) (default=2, minimum=0, maximum=2) 
Defines whether or not the node will broadcast station-identification beacons. The default value of 2 causes station 
identification to be broadcast every 10 minutes. The value of 1 causes station identification to be broadcast only if 
the node has transmitted since the last beacon. A zero (0) will disable station identification. 
NOTE; Many sysops set this parameter to 0 as a means to reduce unnecessary node QRM on the channel. The X-
1J4 node ID's itself each time it sends a packet, so no legal requirement to have ID's turned on. 
Parameter 26 CQ Broadcasts (1=0n, 0=off) (default=1, minimum=0, maximum=1) 
Defines whether or not the node will broadcast AX.25 UI-frames in response to the CQ command. Even if such 
broadcasts are disabled by setting this parameter to zero, the other features of the CQ command continue to operate 
normally. The default value of 1 enables CQ broadcasts. NOTE; When a station connected to an X-1J4 node 
through several distant nodes issues a UI QRA command, the distant node will poll stations that have the QRA 
feature for an ID. After about 40 seconds, the station that sent the polling (UI QRA) can issue the Mheard 
command and receive a list of the station that identified in the area of the distant X-1J4 node that was polled.
