G8BPQ NODE COMMANDS
This document explains the commands available within the Node section
of the G8BPQ switch, and an explanation of the responses.
First the result of inputting an invalid command:
NOTTS:G8BPQ-2} Invalid command - Enter ? for command list
Entering ? produces the following:
NOTTS:G8BPQ-2} BBS CONNECT BYE INFO NODES PORTS ROUTES USERS
Note that BBS is only present if the BBS support is enabled (BBS=1 in
th config file). If you have defined your own applications, they will also
be listed.
The BBS (and your other application names) must be entered in full - all other
commands can be abbreviated to the first character of the command.
Entering BBS (or your own application name) will connect you to the first
free BBS (etc) port, or give an error message if none are available.
The CONNECT command is used to connect you to another node, or to a normal
AX.25 user. To connect to another node, enter C NODECALL or C NODEALIAS.
The system will select the 'best' radio port and neighbour to to use to
reach the required node using its ROUTES and NODES lists.
The format used to connect to another normal user depends on whether you
have more than one radio port. The formats are:
(stuff in [] being optional)
C CALL [via digi1 [digi2...]] If you only have one port
C P CALL [via digi1 [digi2...]] Where P is the port number,
if you have more than 1.
(You can use C 1 CALL if you only have 1 port - its just a waste of typing!)
If you miss out the port number where it is needed, you will get an error
message, listing the available ports.
Normally you cannot override the automatic route selection when you connect
to another node, but you can fool the system into thinking a node is a
normal station by connecting to the alias, and adding an SSID. For example,
if you want to connect to NOTTS:G8BPQ-2, you can force a Level 2 connect
on a secified port by entering C P NOTTS-1
The BYE commnad disconnects you from the switch.
The INFO command sends your INFO text from the config file:
NOTTS:G8BPQ-2} G8BPQ Packet Switch, Mapperley, Nottingham. IO92KX
Commands are basically the same as NET/ROM, but to connect to another
normal station (not another node), you must specify a port number before
the callsign. Use PORTS command to list available ports. The BBS command
connects you to the associated Mailbox.
The PORTS command lists available ports. The descriptions come directly
from the configuration file, and should give at least the frequency and
baud rate used.
NOTTS:G8BPQ-2} Ports:
1 144.650 MHz 1200 Baud (PC120)
2 432.675 MHz 1200 Baud (DRSI)
3 Experimental NET/ROM Link
The NODES command lists all the other NETROM/THENET/BPQ Nodes known to
your node:

By entering N NODECALL (or N NODEALIAS), you can list the routes that
the system will use to access that node:
n rp2
NOTTS:G8BPQ-2} Routes to: RP2:GB3RP-2
100 4 GB3RP-2
23 4 G0GDR-1
19 4 G0GDR-2
The numbers displayed are the 'quality' - the relative desirability of
using this route rather than another, and the Obsolesance Count, an
indication of how long it is since the system was last told about (
or successfully used) this route. The number starts at a value set in
the config file (typically 5) and is decremented each time a 'NODES'
broadcast is sent (typically evey hour).
The ROUTES command lists the stations which this node can hear.
NOTTS:G8BPQ-2} Routes:
2 G4RFG-1 0 0!
1 G4RFG 0 0!
1 GB7LX-2 0 0!
2 GB7LX-7 20 0!
2 G0GDR-1 120 62!
1 G0GDR-2 100 49!
2 G7AXC-7 50 41!
1 GB3RP-2 100 17!
1 G1EUP-8 50 0!
1 GB7LED 50 1!
1 G4XMH-1 50 0!
2 GB7LRG-7 10 0
The first number is the port. The second is the quality. This may be
derived from the 'default quality' parameter in the PORTS section of the
config file, or may be specified explicitly in the ROUTES section.
A value of zero will prevent the route from being used, and is normally
used when you have a one-way or marginal path. The third number is the
number of NODES list entries which refer to this route. This isn't used
by the software - it is just information for the user. The '!' indicates
a 'locked route' - one entered in the CONFIG file. Other entries come and
go as this node hears NODES broadcasts.
The USERS command lists the stations currently using the node.
NOTTS:G8BPQ-2} G8BPQ Network System V3.21 (95)
Host6(NOTTS:G8BPQ-2)
Host3(NOTTS:G8BPQ-2) <--> Circuit(LRG7:G0GDR-1 G8BPQ-1)
Uplink(G9XXX) <~~> Downlink(G9YYY)
Host is an internal (Normally BBS Port)
Circuit is a link from/to another node.
Uplink is a connection from a normal Ax.25 station.
Downlink is a connection to a normal user.
The <--> indicates an active session. <~~> indicates a session being set up.
The Number on the end of the header line is the number of free buffers.
There are a few commands not given in the menu. These are primarily of
interest to the sysop, (or for me to experiment with). They are LINKS,
STATS, L4T1, and PACLEN.
The LINKS command lists the currently active AX.25 Sessions (Both user
access and node-node links)
NOTTS:G8BPQ-2} Links:
G0GDR-1 G8BPQ-2 S=5 P=2 T=3 V=2
S is the link state (see AX25 protocol spec, but the main ones are
2 (connecting) 4 (disconnecting) 5 (connected)).
P is the port.
T is the link type. 1=Uplink, 2=Downlink, 3=Node-Node link.
V is the AX.25 Version (1 or 2).
The STATS command displays a number of counters.
NOTTS:G8BPQ-2}

Most are fairly obvious, but a few need a bit of explanation. There is one
set of level 2 counters for each port.
Time Active is the time since the system was loaded.
Timer Overruns count the number of times the main code (which is initiated
by the timer interrupt) is still running when the next timer interrupt
occured. If it increments very rapidly (several times a minute), it
indicates that the PC is too slow for the amount of data being processed.
It is normal for an XT class machine running a couple of BBS ports to get
about one overrun per minute. My 10MHz AT clone very rarely shows any.
RX Overruns indicate characters lost because the software didn't process
the interrupts fast enough. If you are running KISS ports, and you get
a lot (ie a significant percentage of L2 frames heard), try reducing the
speed of the link from the PC to the TNC. If you are using an HDLC card
(DRSI or PC120), particularly at high speed, then there isnt much you
can do except buy a faster machine. (But I would like to hear from anyone
having problems running at 9600 baud or above - I may be able to speed up
the routines a bit).
TX Underuns indicate a similar problem in responding to TX interrupts,
but only apply to HDLC cards (you cant get a TX underrun on an async port).
Frames abandoned counts the number of frames discarded because they have
been waiting to be sent (for DCD to clear) for more than 60 secs. If a
lot occur, then either your squelch is a bit dodgy, or the channel is
VERY busy. Only used for HDLC cards.
Link Active shows two values for each port. The first is the % of time
in the last minute that your station was transmitting, and the second
the % the channel was active (sum of Transmitting and DCD active). Only
maintained for HDLC ports.
The L4T1 command displays or sets the Level 4 timeout used for the current
session. It is primarily for me to experiment with.
PACLEN sets or displays the PACLEN value used for messages generated by
the node (eg command responses). Again it is mainly for me to play with.
