INTRODUCTION TO PACKET RADIO - PART 11
by Larry Kenney, WB9LOZ
USING THE NODE NETWORK - PART 2 OF 2 COMMANDS
....continued from part 10
ROUTES: The ROUTES command (abbreviated as R) will give you a list
of the direct routes to other nodes from the node you're using. The
direct routes are the ones where the node can connect directly
to the other node. The quality of each route is shown along with
the obsolescence count. (See the NODES command in part 10 for
an explanation of obsolescence count.) Any route marked with an
exclamation point (!) means that the route values have been entered
manually by the owner of the node and it usually means that the
route is not reliable for regular use.
USERS: The USERS command (abbreviated as U) will show you the
callsigns of all the stations now using the node that you're
connected to. There are five descriptions used by the node to
describe how users are connected:
UPLINK: The station indicated is connected directly to the node.
DOWNLINK: The node has made a connection from the first station
to the second station. Example:
DOWNLINK (K9AT-15 N6UWK)
would mean that the node connected to N6UWK at the request
of K9AT. CIRCUIT: Indicates that the station indicated has
connected FROM another node when the node and user callsign
are on the left of the <--> and indicates that the station
has connected TO another node if node is on the right of the
<-->. If you see dashes between the arrows, the circuit is in
use. If you see <~~>, the connection is in progress. The alias
and call of any other nodes being used are shown prior to the
user's callsign. Examples:
Circuit (SFW:W6PW-1 WA6DDM) <--> AA6ZV would mean that
WA6DDM is using this node, that he connected to it from
the SFW node and is now connected to AA6ZV. N6PGH <-->
Circuit (DIA:WB6SDS-2 N6PGH) would mean that N6PGH connected
direct to this node and has connected to the DIA node.
Circuit (SSF2:KA6EYH-2 KK6SD) <~~> (AMCYN:WZ6X-2) indicates
that KK6SD has connected to the node you're using from the
SSF2 node and is now attempting to connect to the AMCYN node.
CQ: See "CQ command" below. HOST: The user is connected directly
from the node terminal. This is seen when the owner of the node
is a user, or the BBS associated with the node is using it to
forward messages.
CQ: The CQ command is used both for calling CQ and for replying to
the CQ of another station. The command is available only in the
latest versions of NET/ROM and TheNet. Enter a ? when connected
to a node to see if it's available there. The CQ command is used
to transmit a short text message from a node, and is also used
to enable stations that receive the transmission to connect to the
station that originated it. The command is entered as: CQ textmessage
The "textmessage" can be any information up to 77 characters long
including spaces and punctuation, and it's optional. In response to a
CQ command, the node transmits the specified textmessage in "unproto"
mode, using the callsign of the originating user as the source and
"CQ" as the destination. As with all node transmissions, the SSID
will be translated; that is, the SSID will be 15-N, where N is the
SSID of the original callsign. WB9LOZ-0 would become WB9LOZ-15,
WB9LOZ-1 would become WB9LOZ-14, etc.
Here is an example of how the node CQ command is used: If station
W6XYZ-3 connects to a node and issues the command: CQ Anybody
around tonight? the node would then transmit: W6XYZ-12>CQ:Anybody
around tonight?
After making the transmission in response to the CQ command,
the node arms a mechanism to permit other stations to reply to the
CQ. A station wishing to reply may do so simply by connecting to the
originating callsign shown in the CQ transmission (W6XYZ-12 in the
example above). Note here that you connect to the station using the
translated SSID. A CQ command remains armed to accept replies for
15 minutes, or until the originating user issues another command
or disconnects from the node.
Any station connected to a node may determine if there are any
stations awaiting a reply to a CQ by issuing a USERS command. An
armed CQ channel appears in the USERS display as: (Circuit, Host,
or Uplink) <~~> CQ(usercall)
The station may reply to such a pending CQ by issuing a CONNECT to
the user callsign specified in the CQ(...) portion of the USERS
display--it is not necessary for the station to disconnect from
the node and reconnect.
Here's what a typical transmission would look like: (bold text =
entered by user)
cmd: C W6PW-1 cmd: *** Connected to W6PW-1 USERS {SFW:W6PW-1}
NET/ROM 1.3 (669) Uplink(K9AT) Circuit(LAS:K7WS-1 W1XYZ) <~~>
CQ(W1XYZ-15) Uplink(WB6QVU) <--> Circuit(SFBBS:W6PW-3
WB6QVU) CONNECT W1XYZ-15 {SFW:W6PW-1} Connected to W1XYZ Hello!
This is George in San Francisco Hi George! Thanks for answering
my CQ. etc.
Users of the CQ command are cautioned to be patient in waiting for
a response. Remember, your CQ will remain armed for 15 minutes,
and will be visible to any user who issues a USERS command at the
node during that time. Wait a few minutes before issuing another CQ
to give other stations a chance to reply to your first one! Don't
be surprised, however, if you don't receive a response. For some
unknown reason, I've found that very few users take advantage of
the feature. When you connect to a distant node, the CQ command is
a great way to start a QSO with a station in that area, but more
users need to be made aware of the CQ feature before it will become
very useful.
BBS: The BBS command (which cannot be abbreviated) is available on
nodes using the G8BPQ software and having an associated packet
bulletin board system. Entering BBS will connect you to the
associated BBS.
IDENT: The IDENT command (abbreviated as I) found on NET/ROM nodes
will give you the identification of the node you're using. INFO: The
INFO command (abbreviated as I) found on TheNet nodes will give you
information about the node, usually the alias, callsign and location.
INFO: The INFO command (abbreviated as I) found on G8BPQ nodes
will give you the identification of the node and a list of the
commands available.
MHEARD: The MHEARD command (abbreviated as M) found on TheNet and
G8BPQ nodes will give you a list of stations heard by the node. If
the node has more than one port, you must specify which port you
want the listing for by entering a space after the M and then the
port number. Examples:
M 1 will give you a list for port 1 M 2 will give you a list
for port 2
Use the PORTS (P) command to get a list of the ports and the
associated frequencies.
PARMS: The PARMS (Parameters) command (abbreviated as P) found
on NET/ROM and TheNet nodes is for the owner's use in determining
how his station is working. It will give you a list of the node's
parameters.
PORTS: The PORTS command (abbreviated as P) found on G8GPQ nodes
will list the frequencies of all ports available.
BYE: The BYE command (abbreviated as B) is available on TheNet
and G8BPQ nodes. It's used for disconnecting from the node. If the
node has other software, you must disconnect using the D command
in your TNC.
?: Entering a ? will give you a list of the commands available on
the node.
Remember, when you are connected to a network of nodes, any commands
you send will be directed to the last node you connected to.
