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). eicon Eiconcard X.25 interface card. Used for public telecom X.25 networks. 2.7.1 attach com Syntax: attach com <num> {slip|ax25|nrs} <label> <mtu> <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. ax25 A standard AX25 connection. All data is packed into ax25 packets before transmitted. Normally a KISS TNC is connected but this type of connection can also be made directly to another computer. nrs NET/ROM slip. To be connected to the port of a 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>] Configures the secondary logical channels on a multiport KISS TNC. <parent> Interface name of the TNC. <chan> Logical channel number <label> A name for this interface <mtu> Maximum transmission unit. The maximum size of a packet to be transmitted over this interface. [<call>] The callsign for this channel 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. Rev R2A, Updated for NET 920212.PE1CHL page 11 Commands in PE1CHL NET 2.8 ax25 2.8.1 ax25 close Syntax : ax25 close <axcb> Initiates a disconnect of an ax25 session. When all packets 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 Syntax : ax25 digipeat [{{on|off}|<intf> [gate]}] 2.8.3.1 ax25 digipeat Shows digipeating status. 2.8.3.2 ax25 digipeat {on|off} Turns digipeating function on or off. This is for "dumb" digipeating on the same interface. 2.8.3.3 ax25 digipeat <intf> [gate] Enables "dumb" digipeating functions for this interface and optionally enables a gateway. 2.8.4 ax25 disconnect Syntax : ax25 disconnect <axcb> Initiates a disconnect of an ax25 session. A DISC packet is sent immediately. <axcb> AX25 control block. A hexadecimal identification number for the connection. Rev R2A, Updated for NET 920212.PE1CHL page 12 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) Example : Rev R2A, Updated for NET 920212.PE1CHL page 14 Commands in PE1CHL NET IF Users P P0 Pmin Pmax Tinc Tmax int 0 64 128 5 64 60 900 144 2 64 128 5 64 60 900 433 5 21 128 5 64 60 900 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 2 digi $CALLSIGN-10 433725 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. Rev R2A, Updated for NET 920212.PE1CHL page 15 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 : ax25 status &AXB IF Rcv-Q Snd-Q Local Remote State 5ba54 int 0 0 SM0IES-15 SM0IES-8 Conn pending 5bc32 433 70 2 SM0ETV-1 SK0MK Connected 5bb21 433 0 0 SK0MK SM0ETV-1 Connected ax25 status 8550c <enter> &AXB IF Local Remote RBWF V(S) V(R) Unack P Retry State 8550c int SM0IES-15 SM0IES-4 0 0 0/0/4 2 00/10 Connected T1: stop/15015 ms; T2: stop/1485 ms; T3: 67045/1799985 ms; T4: stop/0 ms 2.8.15 ax25 start Syntax : ax25 start { bridge | mbox | mheard | netdigi | tnc | tnc2 } Starts different AX25 functions in the program. The function must be connected to one or several callsigns with 'ax25 port' before it can be started. Rev R2A, Updated for NET 920212.PE1CHL page 16 Commands in PE1CHL NET 2.8.15.1 ax25 start bridge Syntax : ax25 start bridge Starts a conference board. You make a connect to the signal and then you can give commands to send text to other connected users etc. 2.8.15.2 ax25 start mbox Syntax : ax25 start mbox [<filename>] Starts a mailbox of the same kind as is found in many TNC:s. The mailbox sends incomming mail to the mailer with SMTP. You can make forwarding towards the mailbox from a large BBS. <filename> is file that will be sent on the INFO command in the mailbox. 2.8.15.3 ax25 start mheard Syntax : ax25 start mheard <num> Starts a mheard service. Make a connect to the signal and a list of heard signals is presented, after that you get disconnected. <num> is the number of signals listed. NOTE ! Since one callsign is listed on each row the listing should not be too long, then it will just scroll of the screen. 2.8.15.4 ax25 start netdigi Syntax : ax25 start netdigi Starts a digipeat function wich uses local acknowledgement for each part of the connection. This means that a missed packet need only be repeated on one part of the connection. 2.8.15.5 ax25 start tnc Syntax : ax25 start tnc "<text>" Starts the function that handles incoming calls directly to the operator. Incoming text is displayed on the screen and the written text is directly transmitted to the other station. <text> is the welcom message sent upon connect. It is possible to have several <text> arguments, these are sent as multiple lines in the welcom message. Rev R2A, Updated for NET 920212.PE1CHL page 17 Commands in PE1CHL NET 2.8.15.6 ax25 start tnc2 Syntax : ax25 start tnc2 <port>[=<intf>[/<kissrx>]] Starts a virtual TNC. If <port> is a real COM port another computer or terminal can communicate with the program as if it was a TNC. If <port> is not a real COM port it can be used in another program in a multitasking enviroment as eg DoubleDos. 2.8.16 ax25 stop Syntax : ax25 stop { bridge | mbox | mheard | netdigi | tnc | tnc2 } Stops the specified AX25 function. The function is still connected to a port and a signal and may be restarted with a new "ax25 start" command. 2.8.17 ax25 t1 Syntax : ax25 t1 [<val>] Display or set the AX.25 retransmission timer. This controls how long time to wait for acknowledgement before resending the packet. The value is in seconds. 2.8.18 ax25 t2 Syntax : ax25 t2 [<val>] Display or set the AX.25 acknowledgement delay timer. This controls how long time you will wait for more packets before acknowledging the ones you have received. This allows for acknowledgement of more than one packet in the same transmission. The value is in seconds. 2.8.19 ax25 t3 Syntax : ax25 t3 [<val>] Display or set the AX.25 idle "keep alive" timer. This controls how long time you will wait without hearing anything from the other station. The value is in seconds. Rev R2A, Updated for NET 920212.PE1CHL page 18 Commands in PE1CHL NET 2.8.20 ax25 t4 Syntax : ax25 t4 [<val>] A timer for all AX.25 connections except those set up with the "connect" command. The connection is automatically disconnected when no packets have been transfered for this time (idle timer).

Rev R2A, Updated for NET 920212.PE1CHL page 42 Commands in PE1CHL NET 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 1 430 6 70 0 0 0 1915 29 0 0 Rev R2A, Updated for NET 920212.PE1CHL page 43 Commands in PE1CHL NET 2.51 setenv 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.

The mail box can also be started manually. The first command reserves a callsign with ssid that shall be used for contacts with the mail box. The second command starts the program function that manages the mail box. It also specifies what file that shall be sent on a INFO command. Example : ax25 port 6 conn sm0ies-8 ax25 start mbox \net\finger\sm0ies.txt 3.2.2 Commands in the mail box 3.2.2.1 Info Shows the text file specified in the activation command. This file should contain information about the system. 3.2.2.2 Send Syntax : send <call> Sends a message to <call>. The message is distributed to the correct mail area or user with the SMTP protocol. 3.2.2.3 Bye Exits the mailbox and disconnects. 3.3 Logging With the "log" command all calls towards the system can be logged.

Rev R2A, Updated for NET 920212.PE1CHL page 52 Commands in PE1CHL NET 3.4 Recording of traffic With the "record" command data coming in to a session can 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 Rev R2A, Updated for NET 920212.PE1CHL page 53 Commands in PE1CHL NET 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 Rev R2A, Updated for NET 920212.PE1CHL page 54 Commands in PE1CHL NET 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. Rev R2A, Updated for NET 920212.PE1CHL page 56 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.
