Commands in PE1CHL NET
1. Semantics
<xxx> : Replaceable discriptor
{xx|xx} : Use one of them
[xxx] : Optional
"xxx" : Commands or parameters referenced in text,
quoted characters
2. Commands
2.1 <--┘
Entering a carriage return (empty line) while in command
mode puts you in converse mode with the current session. If
there is no current session you remain in command mode.
2.2 !
Syntax: ! [/c <command>]
An alias for the "shell" command.
If no parameter is supplied a DOS shell is started.
If the parameter "/c <command>" is supplied this command
is executed directly. The parameter <command> may contain a
full program path.
To execute this command there must be enough memory
available to hold both NET and the other program in memory
simultaneously.
To return to NET give the command "exit".
Example: To start BMAILER
! /c c:\net\bmailer.exe
NOTE! When you are in the DOS shell NET is not processing
any traffic, all communications are locked.
NOTE! If you issue a "! /c <command>" command when you are
logged in as remote sysop you must be very careful so
that the command or program does not require any
further input. Also do not forget the "/c" parameter.
In case you miss anything the system will hang and
must be rebooted.
NOTE! See "Use of watchdog" to see how to protect a system
from hangs.
Rev R2A, Updated for NET 920212.PE1CHL
page 3
Commands in PE1CHL NET
NOTE! The "/c <command>" parameter is a feature in
PC/MS-DOS, it may be with different syntax or may not
exist at all in other enviroments.
2.3 ?
Syntax : ?
An alias for the "help" command.
Shows a list of available commands.
For further help on a specific command there are three
different methods.
1: Type a "?" after the command. eg "route ?"
2: Type the command without parameters. eg "ftp"
3: Type a nonsens parameter after the command.
eg "trace dfghg"
NOTE! Not all commands provide help.
The fault messages of a command may be used as help.
2.4 #
A comment command. The rest of the line is ignored.
2.5 arp
The use of the arp command is not neccesary as long as you
reach the station yourself and does not require any special
way of access, in this case NET can resolve the address on
its own.
If you want access to a station to wich you must use a
digipeater or if you must use netrom, then you also must
use the "arp add" command.
Below follows descriptions of the different arp commands.
Rev R2A, Updated for NET 920212.PE1CHL
page 4
Commands in PE1CHL NET
2.5.1 arp
Displays the "Address Resolution Protocol" (ARP) table.
For each IP address the following information is shown.
IP addr Type Iface Time Q Addr
44.140.0.15 AX.25 144 19 2 [unknown]
44.140.0.83 AX.25 433 0 SM0ORB-3
44.140.0.59 NET/ROM 0 SM0JZT-7
IP addr : A uniqe identifying number, assigned by the
TCP/IP coordinator for the district.
Type : The type of network that is used.
Iface : The actual interface name.
Time : Time to wait for address information. Or time
the address information remains valid.
Not used (zero) for manual entries.
Q : Number of IP frames waiting for information on
wich way to go.
Addr : The network address/name for this IP address.
[unknown] in this field means that the station
has not yet answered on the address request.
2.5.2 arp add
Syntax : arp add <hostid> {ether|ax25|netrom}[:<intf>]
{<etheraddr>|<callsign> [<digis...>]}
Adds an entry to the table. Used for inserting addresses
not reachable via the default routes for unknown addresses.
It is also useful for "hard-wiring" of digipeater paths on
AX.25 interfaces.
<hostid> The IP number within brackets "[44.140.0.14]"
or as a name according to HOSTS.NET.
ether Packets to that address shall go out on
ethernet. Ethernet is connected with a special
board and uses cable (mostly koax) for
communication. Used on PC-LAN:s etc.
ax25 The packets shall be sent on radio as AX25
packets. AX25 interfaces are commected to the
computer via eg a TNC connected to a COM port.
netrom The packets are to be routed through NET/ROM.
The first node is the internal node in NET.
:<intf> The name of an interface. Used if the address
only shall be valid on that interface.
<etheraddr> Ethernet address, a six digit address uniqe to
every ethernet board. Series are given to
manufacturers. Used on interfaces of type
ether.
<signal> Callsign for the receiver. Used on AX25 or
netrom type interfaces.
<digis> Digipeater callsigns may be added to a
callsign.
Rev R2A, Updated for NET 920212.PE1CHL
page 5
Commands in PE1CHL NET
Examples :
NET/ROM : arp add sm5sfg netrom sm5sfg-2
This adds an entry for sm0sfg, packets to this
station is now handed over to the netrom node
within NET. The destination node is "sm5sfg-2",
the path to this node is provided by the NET/ROM
protocoll.
AX25 : arp add sm5sfg ax25 sm5sfg-2 sm5dq sk5um-7 sk5um-2
This adds an entry for sm5sfg, packets to this
station is now transmitted as ax25 packets to
call sm5sfg-2 via the digipeaters sm5dq, sk5um-7
and sk5um-2.
single interface : arp add pc.sm0orb ax25:int sm0orb-4
This adds an entry for pc.sm0orb on the
"int" interface only. On other
interfaces there can be other entrys for
pc.sm0orb.
2.5.3 arp drop
Syntax : arp drop <hostid> {ether|ax25|netrom}[:<intf>]
Removes the entry for <hostid> from the table for the given
interface. If <intf> is given the entry is only removed for
that interface.
2.5.4 arp publish
Syntax : arp publish <hostid> {ether|ax25|netrom}:<intf>
{<etheraddr|callsign>
Inserts a special entry in the table. When a query arrives
for <hostid> the program answers with the given address.
Consider the following situation :
Y ┌───┐ ┌───┐Slip┌───┐
433└─┤TNC├──┤PC1├────┤PC2│
└───┘ └───┘ └───┘
PC1 is connected to AX.25 network 433 while PC2 has no
external connections at all. In order to make the outside
world think that PC2 is available an "arp publish" command
may be used in PC1, the syntax should be :
arp publish PC2 ax25:433 PC1
This must be combined with a arp add command for the real
address on "slip" so that PC1 knows were to send the frames.
arp add PC2 ax25:slip PC2
Rev R2A, Updated for NET 920212.PE1CHL
page 6
Commands in PE1CHL NET
Use arp publish with great caution since it can mess things
up.
Example :
Y 144 Y
│ ┌─┴─┐ ┌───┐Slip┌───┐
433└────┤TNC├─┤PC1├────┤PC2│
└───┘ └───┘ └───┘
If you want to use the callsign sm0ncs with different SSID
on 144 and 433 you can do it the following way in PC1:
arp add pc2 ax25:slip sm0ncs-13 # lets PC1 find the way
# to PC2
arp publish pc2 ax25:433 sm0ncs-7 # makes PC1 answering on
# an address request
# about PC2 with the
# address SM0NCS-7 if the
# request arrived on 433
arp publish pc2 ax25:144 sm0ncs-2 # makes PC1 answering on
# an address request
# about PC2 with the
# address SM0NCS-2 if the
# request arrived on 144
With this arrangement PC1 will answer to an address request
for PC2. This means that PC2 will seem to be available and
have the callsign sm0ncs-2 on 144 and sm0ncs-7 on 433.
NOTE! The callsigns and SSID:s used must have been assigned
to ports in attach commands.
2.6 at
Syntax: at hh:mm [<command>]
Executes the specified command at the specified time each
day. If no command is given a previusly given command for
the specified time is cancelled. By using the "source"
command a whole sequence of commands can be executed.
This can be used to perform unattended maintanence tasks or
downloads. For example listing all new mail in the BBS at
night and save it in a local mail.
2.7 attach
The attach command is used to attach and configure hardware
to the program. The possible hardware types are :
com Standard PC COM port
kiss Secondary channels in a multiport KISS TNC
netrom Netrom compatible node
Rev R2A, Updated for NET 920212.PE1CHL
page 7
Commands in PE1CHL NET
scc DRSI,EAGLE,PC-100 or PRIMUS boards
packet FTP Inc. "Packet driver" interface for external
drivers, drivers exists for most ethernet cards and
for some other interfaces (AX.25, KISS, SLIP).

<speed> <handshake> [<call>]
Attach and configure a PC:s COM port.
<num> The port number 1-8
slip A slip link port connected to another computer
directly or via a modem. IP frames are sent
without packing into AX25 packets. You can't
use AX25 specific commands on a slip link.

TNC2 running NET/ROM.
<label> A name for this interface
<mtu> Maximum transmission unit. The maximum size of
a packet to be transmitted over this interface.
<speed> Speed for the com port.
<handshake> h/n (hardware / none) the type of handshaking
that shall be used.
[<call>] Callsign for this interface. Only neccesary on
AX.25 and NRS.
The actual hardware address of the COM port is not
specified since the program uses a FOSSIL driver that
handles all hardware specifics.
Example : attach com 1 ax25 144MHz 256 2400 n sm0orb-2
2.7.2 attach kiss
Syntax: attach kiss <parent> <chan> <label> <mtu> [<call>]

Rev R2A, Updated for NET 920212.PE1CHL
page 8
Commands in PE1CHL NET
NOTE! You must first attach a COM port before this version
of the attach command can be used.
Example : attach kiss 144MHz 1 433MHz 256 sm0orb-7
2.7.3 attach netrom
Syntax: attach netrom [<callsign>]
Activates the NET/ROM node. If <callsign> is given this
sets the callsign for the NET/ROM node,
else the NET/ROM function uses the callsigns of the ports.
See the "netrom" command for the rest of the definitions
for the NET/ROM node.
2.7.4 attach scc
Syntax: attach scc <chips> init <base> <sp> <A> <B> <D>
<ia> <iv> {p<clk>|r<clk>} [<o>]
attach scc <num> {slip|kiss|ax25} <label> <mtu>
<speed> [<call>]
2.7.4.1 Initialisation
The first syntax is used for an initialisation call of the
driver. This initialises the circuits and sets up the
configuration.
<chips> Number of SCC chips on the board
<base> Base address of the first chip
<sp> Address spacing between chips
<A> Offset from base address of chip for control
register for port A
<B> Offset from base address of chip for control
register for port B
<D> Offset from control register to data address
<ia> Address of INTACK latch. By writing to and then
reading this address the interrupt vector can be
found. On PC-100 boards only a read is made.
Vectored interrupts can be used only on the Atari
SCC interface, the PA0HZP OptoPcScc card and the
PC-100.
<iv> Interrupt number
p<clk> Crystal clock frequency
r<clk> Rs232 RxC clock frequency
<o> 1 : EAGLE
2 <n> : PC-100
Rev R2A, Updated for NET 920212.PE1CHL
page 9
Commands in PE1CHL NET
4 <n> : PRIMUS
8 : DRSI PC*Packet
<n> Modem control byte according to hardware
Example: Possible initialisation commands are:
EAGLE: attach scc 1 init 2e8 8 2 0 1 0 2 p3686400 1
PC-100: attach scc 1 init 2e8 16 6 4 1 0 2 p4915200 2 22
PRIMUS: attach scc 1 init 2e8 4 2 0 1 0 2 r2457600 4 02
DRSI: attach scc 1 init 300 16 2 0 1 0 2 p4915200 8
2.7.4.2 Channel allocation
When the driver is initiated you can allocate the channels
in the SCC circuits and decide to what they shall be used.
This is done differently depending on the mode they shall
operate in, SLIP, KISS or AX25.
<num> tells what channel that shall be allocated:
0 = SCC 1 A side
1 = SCC 1 B side
2 = SCC 2 A side
3 = SCC 2 B side
etc...
<label> The name of the interface.
<mtu> Maximum transmission unit. Largest packet that
kan be transmitted on the channel.
<speed> The speed of the channel.
<call> The callsign to be used on the channel.
SLIP
Syntax : attach scc <num> slip <label> <mtu> <speed>
Connects a SLIP link to another computer. The speed can be
read with the command "param <label>" and changed with the
command " param <label> <speed>".
NOTE! No signal is used on the SLIP link.
Example : attach scc 0 slip intern 512 9600
param intern 4800
KISS
Syntax : attach scc <num> kiss <label> <mtu> <speed> <call>
Is used to connect a KISS TNC or a computer running NET to
the channel. Since the KISS protocol is AX25 based you can
make AX25 connects over it.
Rev R2A, Updated for NET 920212.PE1CHL
page 10
Commands in PE1CHL NET
With the command "param <label> <parameter> <value>" you
can change parameters in the KISS TNC.
Example : attach scc 1 kiss extern 236 1200 sm0orb-3
param extern 1 35
AX25
Syntax : attach scc <num> ax25 <label> <mtu> <speed> <call>
This allocates a logical KISS TNC emulator to the channel.
The parameters are the same as for the KISS initialisation.
The result is that you get AX25 packets ready to broadcast
directly from the board. If the board contains a modem all
you need to add is the radio.
You can also set parameters in the emulated KISS TNC as
with a normal KISS TNC.
Exempel : attach scc 0 ax25 DRSI-A 236 1200 sm0orb-2
2.7.5 attach escc
Syntax: attach escc <port> <label> <mtu>
This attaches an Eiconcard. The card must be initialized
with the X.25 network software before starting NET.
2.7.6 attach packet
Syntax: attach packet <int#> <label> [<buffers> [<mtu>]]
Attaches an inteface to a "Packet Driver". This is a driver
for a network card. Drivers exists for the most common
cards and must be activated before NET is started.
<int#> Number of the software interrupt used to
communicate with the driver. Must match the
value given at installation. The value can be
#60-#7F.
<label> A name on the inteface.
<buffers> Max number of buffers stored
<mtu> Maximum Transmission Unit. Max size of packets
transmitted over this interface.

in the send que is acknowledged a DISC packet is sent.
<axcb> AX25 control block. A hexadecimal identification
number for the connection.
2.8.2 ax25 calls
Syntax : ax25 calls
Shows a list of all callsigns the program listens for and
the purpose the callsign is used for.
2.8.3 ax25 digipeat

Commands in PE1CHL NET
2.8.5 ax25 exclude
Syntax : ax25 exclude [<call> [{<intf>|d}]]
Is used to exclude certain signals from the stations on one
or all interfaces. The function should be used very
carefully to avoid angry reactions, but may be useful to
prevent stations from connecting on interfaces reserved for
forwarding or so.
2.8.5.1 ax25 exclude
If no more parameter is given the excluded callsigns and
the interfaces they are excluded on is shown.
Example : ax25 exclude
Callsign Interface
SM0IES 144
2.8.5.2 ax25 exclude <call> [<intf>]
This excludes the given signal. If <intf> is given the
signal is only excluded on that interface, else on all
interfaces.
Example : ax25 exclude sm0ies 144
2.8.5.3 ax25 exclude <call> d
Removes the signal from the list of excluded signals.
2.8.6 ax25 kick
Syntax : ax25 kick <axcb>
Forces transmission of unacknowledged packets in the
specified connection. This can be used to wake up a
connection that has been "locked up" in the other end.
Example :
Rev R2A, Updated for NET 920212.PE1CHL
page 13
Commands in PE1CHL NET
ax25 status <enter>
&AXB IF Rcv-Q Snd-Q Local Remote State
5ba54 int 0 2 SM0IES-15 SM0IES-8 Connected
ax25 kick 5ba54 <enter>
2.8.7 ax25 maxframe
Syntax : ax25 maxframe [<num>]
Max number of packets allowed to be unacknowledged. This
controls how many packets that can be transmitted together.
A higher value gives better datarate on a good connection
but can make it very hard to keep a connection on a havily
loaded channel.
If <num> is not given the current value is shown. Else it
is set to <num>. <num> must be 1-7.
2.8.8 ax25 paclen
Syntax : ax25 paclen [<num>]
Sets maximum packet length for AX25 interfaces. Other
protocols, like NET/ROM, or channel conditions can make it
neccesary to limit the maximum packet size below 255.
2.8.9 ax25 persist
Syntax : ax25 persist [<intf> [<p0> [<pmin> [<pmax>
[<tinc> [<tmax>]]]]]]
If no more parameter is given a table is shown with the
values for all interfaces. If <intf> is given the values
given vill be set. The persistence value is calculated as:
"p = p0 / number of active users" and is limited by "pmin"
and "pmax". "tinc" is a time added to the time a user is
counted as active for each packet received, this time is
limited by "tmax".
<intf> The name of the interface
<p0> Initial value for persistence
<pmin> Minimum value for persistence
<pmax> Maximum value for persistence
<tinc> Time increment for each packet (in seconds)
<tmax> Maximum user active time (in seconds)

2.8.10 ax25 port
Syntax : port <portno> {conn|digi} <callsign> [intf]
[{gate|multi}]
Attaches the callsign to a given ax25 port function
according to the following list.
1=TNC Connects to the console
2=NetDigi A digipeater function with local ack
3=MHEARD Gives a heard list
4=Bridge Conference bridge
5=TNC2 TNC-2 emulator
6=AX25-MailBox A simple mailbox
conn The definition is used when call is found in connect
field of signal
digi The definition is used when call is found in
digipeat field of signal
gate Shows that the function can act as a gateway
multi Allows multiple connects.
Example :
ax25 port 1 conn $CALLSIGN
ax25 port 2 digi $CALLSIGN
ax25 port 4 conn $CALLSIGN-1
ax25 port 6 conn $CALLSIGN-8
ax25 port 2 digi $CALLSIGN-9 144625 gate

ax25 port 3 conn $CALLSIGN-9 144625 multi
ax25 port 3 conn $CALLSIGN-10 433725 multi
ax25 port 5 conn $CALLSIGN-12
2.8.11 ax25 pthresh
Syntax : ax25 pthresh [<size>]
When no reply is received on an AX.25 I packet, it will be
re-sent as a I(P) packet if it is smaller than <size>. When
the packet is larger, an RR(P) poll will be done first.
After 3 tries, the program will always do RR(P) polls, also
for small packets.

Commands in PE1CHL NET
2.8.12 ax25 reset
Syntax : ax25 reset <axcb>
Breaks up an AX25 connection in a very nasty way. No
information is sent to inform the other end of the
connection about what happened, leaving it hanging in
vaccum. If further packets for the connection arrives they
will be answered with a "DM" packet.
2.8.13 ax25 retry
Syntax : ax25 retry [<num>]
Shows how many attempts that are made to send a packet to
the remote station. If the packet is not acknowledged after
theese attempts the connetction is disconnected. If <num>
is given the number of attempts are set to its value.
2.8.14 ax25 status
Syntax : ax25 status [<axcb>]
Without an argument, displays a one-line summary of each
AX25 control block. If the address of a particular control
block is specified, the contents of that control block are
dumped in more detail. Note that the send queue units are
frames, while the receive queue units are bytes.
Example :

2.50 sccstat
Once the SCC driver has been initialized, some statistic
information can be shown using the sccstat command. The
output of this command shows one line of information per
attached channel.
The info shown is :
Ch - channel number of the attach command
Iface - name of the interface
Sent - number of frames queued for transmission
Rcvd - number of frames received correctly
Error - number of receive errors (CRC, ABORT)
Space - number of times the receiver buffer pool was found
empty
Overr - number of receiver overruns and transmitter
underruns
Rxints - number of receiver interrupts
Txints - number of transmitter interrupts
Exints - number of receiver special condition interrupts
Spints - number of external/status interrupts
It is normal that a SLIP or KISS channel shows no errors,
and no special condition or external/status interrupts,
while an AX25 channel has lots of these.
An overrun is abnormal for all operating modes. If lots of
these occur, the product of baudrate and number of
interfaces is too high for the processing power of your
computer.
If "Space" errors occur, specify a higher number of buffers
in the "buffers" command. It is, however, normal if these
errors occur when you start a shell, or when you pause the
output of any command using CTRL-S. This is because the
processing and allocation of buffers stops in these cases,
while receiver input keeps coming in under interrupt
control.
When you see only transmitted frames, the number of
transmitter interrupts is 1, and all other counters are 0,
the SCC is not generating interrupts to the computer. The
single transmitter interrupt is a "simulated" interrupt
that should start the transmission (but apparently
doesn't).
Example :
Ch Iface Sent Rcvd Error Space Overr Rxints Txints Exints Spints
0 144 88 152 200 0 0 10013 4488 905 235

Syntax : setenv <envname>=<string>
Sets the value of a DOS ENVIROMENT VARIABLE. <envname> is
the name of the variable and <string> the value it gets. To
remove a variable assign it an empty string.
Enviroment variables are used by NET and other programs to
hold values that differ between two installations of the
program but are constant in one specific installation.
Enviroment variables can also be set from DOS, use the
command SET.
2.52 shell
Syntax: shell [/c <command>]
Also available as the alias "!"
If no parameter is supplied a DOS shell is started.
If the parameter "/c <command>" is supplied this command
is executed directly. The parameter <command> may contain a
full program path.
To execute this command there must be enough memory
available to hold both NET and the other program in memory
simultaneously.
To return to NET give the command "exit".
Example: To start BMAILER
! /c c:\net\bmailer.exe
NOTE! When you are in the DOS shell NET is not processing
any traffic, all communications are locked.
NOTE! If you issue a "! /c <command>" command when you are
logged in as remote sysop you must be very careful so
that the command or program does not require any
further input. Also do not forget the "/c" parameter.
In case you miss anything the system will hang and
must be rebooted.
NOTE! See "Use of watchdog" to see how to protect a system
from hangs.
NOTE! The "/c <command>" parameter is a feature in
PC/MS-DOS, it may be with different syntax or may not
exist at all in other enviroments.

be saved to a file. The most common use of this is to enter
a BBS and read a message to a file for future study.
This is how to do it:
1. Connect the BBS and choose the letter you want to
record.
2. Press F10 to get the "net>" prompt back.
3. Give the command "record <file>".
4. Press "ENTER" on an empty line and you are returned to
the BBS (nothing shows though).
5. Give the command to the BBS to read the message.
6. Press F10 and give the command "record off" to finish
recording, the message is now saved in a file with the
name you gave at <file>.
NOTE ! Messages from the system, eg. regarding new mail,
that comes in during recording is also saved in the
file.
3.5 Digipeater
3.5.1 Setting up digipeaters
Two commands are neccesary in autoexec.net or a file called
by it. The first command reserves a callsign or ssid for
the digipeater, the other activates the netdigi program
function.
Example :
ax25 port 2 digi $CALLSIGN
ax25 start netdigi
3.5.2 Setting up gateways
One command is neccesary for each frequency that is to be
reached by a gate. These commands reserves a callsign or
ssid for each out frequency. Also needed is a command to
activate the netdigi program function, this may be the same
as for the digipeater function.
Example :
ax25 port 2 digi $CALLSIGN
ax25 port 2 digi $CALLSIGN-9 144625 gate
ax25 port 2 digi $CALLSIGN-10 433650 gate
ax25 port 2 digi $CALLSIGN-11 144675 gate
ax25 port 2 digi $CALLSIGN-12 433725 gate
ax25 start netdigi

3.5.3 To use the digipeater
Using a digipeater in NET is almost as using an ordinary
digipeater. The major differences are that the digipeater
in NET acknowledges all packets localy on each part of the
connection and that NET send out a couple of extra lines
when the connection is set up.
Example :
Connect via ordinary digipeater:
C SM5DQ V SM0ORB
After all packets has gone back and fort in each direction.
*** CONNECTED to SM5DQ VIA SM0ORB
The connection is established
Connect via NET:s digipeater:
C SM5DQ VIA SM0ORB
A quick answer
*** CONNECTED to SM5DQ via SM0ORB
NetDigi SM0ORB: Please wait for connection
When NET has made the connect on the other side
NetDigi SM0ORB: CONNECTED to SM5DQ
The connection is established
Local acknowledgement is an advantage if one part of the
connection is poor since fewer packets need to be
retransmitted because of that poor connection.
3.5.4 To use the gateway
In an ordinary TNC a callsign or ssid is used to indicate
that the connection is to be set up from one channel to the
other. This provides a cross form connection possibility
with one callsign. In NET a callsign or ssid is used to
indicate the outgoing interface for the connection
regardless of the incoming interface. This construction
allows more than two interfaces to be used.
Example:
C SM5DQ SM0ORB-9
Connection part between SM0ORB and SM5DQ is on 144625
C SM5DQ SM0ORB-10
Connection part between SM0ORB and SM5DQ is on 433650

3.6 NET/ROM Node
NET/ROM Node commands
3.6.1 Through connect
The node may be used as an intellegent digipeater. A direct
connect to a station can be made by giving a connect
command of the form:
connect <call> via <entrynode> <exitnode> or
connect <call> via <node>
This gives a connect to the entry node. That node sets up
the path to the exit node and makes the connect to the
destination call. If there is any problems when setting up
the path the entry node returns DM (busy). If only one node
is specified it is used as both entry and exit node.
3.7 Multiple sessions
When an outgoing connection has been established all text
written is sent to the opposite end of that connection. If
you wish to give commands to NET you can press F10 to
return to the command prompt. There you may start a new
outgoing connection.
Every connection is given a session number and with the
session command the existing sessions may be listed. By
providing a session number to the session command you
return to that session and continues to send text on that
connection.
Keep in mind that each session has a limited buffer for
storing incoming text, when that buffer is full
communication is stopped.
The most common use is to create several FTP sessions so
that several files can be transferred simultaniusly.
3.8 Transfer mail to a file
When the first line of a "mailbox" file (mail\xxxx.txt) is
of the form:
{write|append} [<path>\<file>
the incoming mail will be written (or appended) to the
specified file, not to the mailbox file.
Example :
The file HOSTS.TXT reads:
write c:\net\hosts.net
This makes the hosts list sent to HOSTS@<signal> to be
written to the file NET uses.
Rev R2A, Updated for NET 920212.PE1CHL
page 55
Commands in PE1CHL NET
The file DIGEST.TXT reads:
append c:\net\public\digest.txt
This makes mail sent to DIGEST to be stored in a file that
can be fetched with FTP. The file is updated when new mail
arrives but old mail is not deleted.
3.9 Forwarding to AX.25 BBS
When mail must be sent to a host, a check is made if the
hostname is of the form "<call>.bbs", and if a file exists
in the MQUEUE directory with this name. If both of these
conditions are met, the mail is forwarded using a script in
the MQUEUE\<call>.bbs file.
The script contains lines, of which the first character is
an opcode :
# This line is a comment.
c Only as the first line: Specifies the initial
connect to be made. This can be a connect to the
BBS, or to a NET/ROM node that is used to reach the
BBS. Syntax is like the net> connect command.
s Send string to remote BBS or node. Can be used to
send strings containing connect commands to NET/ROM
nodes.
w Wait for specified string to be received. Lines not
containing this string are ignored. Useful during
connect and disconnect phase, to eat banners sent by
the BBS.
r Checks for a specified string to be received. When a
line not containing this string is received in the
message transfer phase, it is mailed back to the
message sender (it probably is an error). While in
the connect phase, the box is simply disconnected.
l Marks the point in the script where the connect
ends, and the messages are transferred. ("loop")
m Defines the line to be sent to send a message. Line
is used as an argument to sprintf, with the
following string args:
1. message type ("P")
2. destination call
3. destination bbs
4. source call
5. message id
u Send subject of message. Line is an argument to
sprintf, with the message subject as an argument.

Commands in PE1CHL NET
b Send the body of the message. Any text after the "b"
is sent as the end-of-message marker. The default is
^Z.
n Defines the end of the message transfer lines and
the start of the disconnect phase. Control will
branch back to "l" when more messages are to be sent
("next")
4. Configuration
