_________________________________________________________________
netrom acktime [<millisecs>] Default: 3000
_________________________________________________________________
Display or set the NET/ROM acknowledge timer. (This is analagous
to the AX.25 T2 timer).
>> Example: netrom acktime 3000
________________________________________________________________
netrom bcnodes <interface>
________________________________________________________________
Set the interface to be used for NET/ROM routing table
broadcasts.
>> Example: netrom bcnodes tnc0
_________________________________________________________________
netrom connect <node_callsign>|<node_alias>
_________________________________________________________________
Make an ordinary NET/ROM connection to another NET/ROM node
(which may be an ordinary NET/ROM, or may be the NET/ROM node at
another NOS station).
The target node may be specified as a callsign or as a NET/ROM
alias.
>> Examples: netrom connect NR9ABC-2
netrom connect #PARIS
_________________________________________________________________
netrom choketime [<millisecs>] Default: 180000
_________________________________________________________________
Display or set the NET/ROM choke time. This is the time to wait
before breaking a send choke condition.
>> Example: netrom choketime 100000
_________________________________________________________________
netrom derate [on|off] Default: on
_________________________________________________________________
Display or set the NET/ROM derate mode. This is an experimental
command to attempt to overcome the severe NET/ROM limitation of
single-path-only operation. That is, normal NET/ROM only tries
alternative routes for traffic IF a link actually fails.
If derate is set to 'on' and retries on a particular link occur,
the NET/ROM quality for the link will be slowly reduced. If then
another path gets to have a better quality, that path is
attempted.
>> Example: netrom derate on
_________________________________________________________________
netrom interface <interface> <alias> <quality>
_________________________________________________________________
The 'netrom interface' command specifies an <interface> to be
used for NET/ROM, together with the NET/ROM node <alias> and
<quality>.
The <alias> is a string of up to six characters, and is the name
by which the node is known to other NET/ROM stations. There are
no hard and fast rules for choosing an alias name, but ideally it
should contain the letters "IP" or "TCP", or start with a "#", to
make it clear to other users that this is not an ordinary NET/ROM
node. A suggested convention is to incorporate the last half of
your IP address, expressed in hexadecimal, into the alias.
The <quality> is the default quality for incoming NET/ROM
broadcasts (and is also the default quality for stations added to
the node filter list).
>> Example: netrom interface tnc0 #BOB 191
_________________________________________________________________
netrom irtt [<millisecs>] Default: 15000
_________________________________________________________________
Display or set the NET/ROM Initial Round Trip Timer.
>> Example: netrom irtt 5000
_________________________________________________________________
netrom kick <&CB>
_________________________________________________________________
Kick the NET/ROM session with control block address <&CB>.
>> Example: netrom kick 86780008
_________________________________________________________________
netrom load
_________________________________________________________________
Load the NET/ROM routing table (N:\NETROM.SAV), saved earlier
with the 'netrom save' command.
_________________________________________________________________
netrom minquality [<n>] Default: 10
_________________________________________________________________
Display or set the minimum acceptable quality of incoming NET/ROM
broadcasts. <n> must be in the range 1 to 255.
>> Example: netrom minquality 10
_________________________________________________________________
netrom nodefilter
_________________________________________________________________
Display the node filter list.
>> Example of 'netrom nodefilter' display output:
.....................................................
: NS9GWA-5 tnc0 10 NS9GWB-5 tnc0 100 :
:...................................................:
_________________________________________________________________
netrom nodefilter add <neighbour_callsign> <interface>
[<quality>]
_________________________________________________________________
Add a node to the node filter list.
The default value of <quality> is the quality value assigned in
the 'netrom interface' command.
>> Example: netrom nodefilter add NR9AAA-2 tnc0 20
_________________________________________________________________
netrom nodefilter drop <neighbour_callsign> <interface>
_________________________________________________________________
Remove a node from the node filter list.
>> Example: netrom nodefilter drop NR9AAA-2 tnc0
_________________________________________________________________
netrom nodefilter mode [none|accept|reject] Default: accept
_________________________________________________________________
Display or set the node filter mode. The settings are:
none: No filtering. The filter is ignored.
accept: Only nodes in the nodefilter list will be heard by the
node.
reject: Nodes in the nodefilter list will be rejected. This is
used to disable a path to a neighbouring node; useful if there
are several paths and you do not want to use a specific one.
>> Example: netrom nodefilter mode accept
_________________________________________________________________
netrom nodetimer [<seconds>] Default: 0
_________________________________________________________________
Display or set the NET/ROM route update broadcast interval.
>> Example: netrom nodetimer 1800 (for half-hourly broadcasts)
_________________________________________________________________
netrom obsotimer [<seconds>] Default: 0
_________________________________________________________________
Display or set the NET/ROM obsolescence timer, which indicates
how long the entries will remain alive in the NET/ROM routing
table.
A new or refreshed entry in the table has a time-to-live (TTL)
count of 6. Each time the obsotimer expires, the TTL count is
decremented by one. If node information is not refreshed, the
entry will eventually disappear when the TTL count falls to zero.
>> Example: netrom obsotimer 1200 (for a 2-hour lifetime)
_________________________________________________________________
netrom promiscuous [on|off] Default: off
_________________________________________________________________
Display or set NET/ROM "promiscuous" mode. This determines
whether or not the node will listen to all routing table
broadcasts, irrespective of quality.
>> Example: netrom promiscuous on
_________________________________________________________________
netrom qlimit [<bytes>] Default: 2048
_________________________________________________________________
Display or set the maximum number of bytes on the NET/ROM receive
queue. This is the threshhold at which the sender is choked.
>> Example: netrom qlimit 1024
_________________________________________________________________
netrom reset <&CB>
_________________________________________________________________
Reset the NET/ROM session with control block address <&CB>. Use
the 'netrom status' command to obtain the control block address.
>> Example: netrom status 86780008
_________________________________________________________________
netrom retries [<n>] Default: 10
_________________________________________________________________
Display or set the maximum number of connect and disconnect
retries.
>> Example: netrom retries 5
_________________________________________________________________
netrom route
_________________________________________________________________
Display the NET/ROM routing table. Entries are of the form
<alias>:<callsign>.
>> Example of 'netrom route' output:
.................................
: #LIZ:NS9LIZ-5 #JIM:NS9JIM-5 :
:...............................:
_________________________________________________________________
netrom route add <alias> <target_callsign> <interface> <quality>
<neighbour_callsign>
_________________________________________________________________
Add an entry to the NET/ROM routing table.
The <alias> and <target_callsign> apply to the station at the
eventual destination of the route.
The <neighbour_callsign> is the callsign of the local NET/ROM
node to which packets will be sent first on their journey to the
target.
>> Example: netrom route add #GWA NS9GWA-5 tnc0 192 NR9AAA-2
_________________________________________________________________
netrom route drop <target_callsign> <neighbour_callsign>
<interface>
_________________________________________________________________
Remove an entry from the NET/ROM routing table.
>> Example: netrom route drop NS9GWA-5 NR9AAA-2 tnc0
_________________________________________________________________
netrom route info <target_callsign>
_________________________________________________________________
Display NET/ROM routing information. The output includes the
quality, TTL, interface and neighbouring NET/ROM node. Permanent
routes which have been manually entered are indicated with a "P".
>> Example of output from 'netrom route info NS9GWA-5':
..................................
: P 50 6 tnc0 NR9AAA-2 :
:................................:
_________________________________________________________________
netrom save
_________________________________________________________________
Save the current NET/ROM routing table in N:\NETROM.SAV.
_________________________________________________________________
netrom status [<&CB>]
_________________________________________________________________
Display NET/ROM status.
The 'netrom status' command without a control block parameter
<&CB> displays the general status.
>> Example of 'netrom status' output:
................................................................
: &CB Snd-W Snd-Q Rcv-Q LUser RUser @Node State :
: 86780008 0 0 0 NS9BOB-5 Listening :
:..............................................................:
When a control block address is supplied, a more detailed
outputis produced.
>> Example of output from the command 'netrom status 86780008':
.........................................................
: Local: NS9BOB-5 0/0 Remote: @ 0/0 State: Listening :
: Window: 0 Rxpect: 0 RxNext: 0 RxQ: 0 :
: Unack: 0 Txpect: 0 TxNext: 0 TxQ: 0 :

isrecommended for amateur radio work.
>> Example: netrom timertype linear
_________________________________________________________________
netrom ttl [<hops>] Default: 10
_________________________________________________________________
Display or set the NET/ROM Time-to-Live. This is the maximum
number of hops a packet can take before it is thrown away. This
prevents packets from circulating for ever in an endless loop.
>> Example: netrom ttl 15

netrom user [<username>] Default: ax25 mycall
_________________________________________________________________
Display or set your NET/ROM user name.
>> Example: netrom user NS9JIM-5
_________________________________________________________________
netrom verbose [on|off] Default: off
_________________________________________________________________
Display or set the NET/ROM "verbose" mode. When set to 'on', the
node will act as a normal NET/ROM switch, broadcasting its
routing table in the normal NET/ROM manner.
>> Example: netrom verbose on
_________________________________________________________________
netrom window [<frames>] Default: 4
_________________________________________________________________
Display or set the maximum NET/ROM window size. This is the
largest negotiable send and receive window.
>> Example: netrom window 4
