- Connecting to other stations
-
- LAN-LINK lets you minimise the keystrokes necessary to connect to
- another station. There are several ways to connect to the other
- station as described below. Howver before you connect to someone
- else, remember that LAN-LINK treats incoming connects and outgoing connects
- differently. To connect to another station, Use the Alt-C
- hot key, Function key 5 (F 5), or bring up the Call Menu by touching the
- 'Esc' key and choosing the 'C' option. DO NOT TYPE
-
- 'C Callsign'
-
- in the command mode. If you do, the
- connect will still take place (the TNC won't know if you or
- LAN-LINK issued the command) but LAN-LINK will treat it as
- an incoming connect and issue the "[ZCZ] LAN-LINK 1.56>"
- handshaking signal (if the LAN-LINK flag is in its default,
- or enabled state). If you connect to a BBS or a Node this way,
- you will get an error message back from the BBS or node, since it
- does not recognize LAN-LINK's handshake.
-
- When you use the Alt-C or F5 approach you can also make use
- of the 'path memory' feature in the LAN-LINK.DIR file.
-
-
- Point and Shoot MH List
-
- You use the F5 approach to connect to a station that you have heard.
- When you touch Function key 5, LAN-LINK sends a 'MH' command to the
- TNC and the MH list shows up in a special window and freezes until
- you depress any key. While the list is frozen, LAN-LINK is
- not monitoring received data, so don't freeze it too long. Move the
- cursor to the desired callsign. When the cursor is positioned on
- any character in the call, press the 'Enter' Key and that call
- will be recognized as the callsign. If the call is joined to the
- word "Cmd:" or the cursor is positioned on a space or blank,
- the connect attempt will be inhibited.
-
- Using the Call menu
-
- When you use the Alt-C hot key or the The Call Menu LAN-LINK will remember
- the previous 15 calls and you may use the Up and Down arrows to move the
- cursor to a remembered call. If you wish to capture a call from the incoming
- text window, push Function Key 10 (F10) to enter the window and
- move the cursor to the desired callsign. When the cursor is
- positioned on any character in the text, push the 'Enter' Key and
- that word will be recognized as the callsign. Any characters
- joined to the call (such as a '.') will be picked up as part of
- the call. If the cursor is positioned on a space or blank, the
- connect attempt will be inhibited.
-
- In AMTOR, whenever you are asked to enter a callsign, LAN-LINK
- will prompt you with its guess at the SELCAL. If you agree with
- it, just press the 'Enter' Key, if you disagree, enter your
- choice over the prompt version.
-
- Names, Handles and Paths
-
- If you so desire, you can create a directory file
- (default name is LAN-LINK.DIR) and keep a list of names
- and calls. The computer will look up a name and call
- the station by its callsign. For example if you put
-
- Joe G3ZCZ
-
- as a line in the file, when you tell the computer to
- connect to Joe, it will try to connect to G3ZCZ. If
- you enter
-
- 4X4HF 4X4HF V 4X1AA, 4Z4ZB, 4X4IL
-
- you only need to type '4X4HF' to set up the correct
- connect path.
-
- You can also use this feature to automate a NET/ROM
- and/or a KA Node path connection.
-
- NET/ROM and TheLink
-
- In the manual NET/ROM path setting up mode, you would
- first connect to your local node, then when you are
- connected with it, connect to the next node, and so on
- through any intermediate nodes within the whole path
- before you finally connect with your destination
- station. You may also have digipeaters in any of the
- paths.
-
- For example if you wish to connect to K1HTV who is in
- range of the SSCT node, and you are in Washington DC,
- you might first have to connect to your local NET/ROM
- node (ELK) via a digipeater, then each of the
- intermediate nodes, SNJ3, NNJ, WMA before you could try
- to connect with K1HTV.
-
- Consider the manual sequence to make the connection.
- K1HTV is the station the contact is being attempted
- with, and he is located within range of the SCCT
- NET/ROM node. The station attempting the connect is
- located in the Washington DC area one digipeat away
- from the ELK NET/ROM node.
-
- The connection to the local node is performed first.
- The operator has to type 'C ELK v WB4APR-5' to make
- that link. When the connect with the node is achieved,
- the operator must type 'C SNJ3' to connect to the next
- node. Each time the connection is made, the operator
- must type in the command to make the next one, until
- finally the last node is reached and a connect request
- can be made to the destination station (either direct
- or via a digipeater). Sometimes there may be an
- intermediate non-NET/ROM connection between two
- stations somewhere in the path.
-
- This procedure is tedious and time consuming, because
- it may take several seconds to complete each stage of
- the link. LAN-LINK automates this sequence by scanning
- the line in the LAN-LINK.DIR file associated with the
- callsign entered and transmitting each section of the
- line when it recognizes the 'Connected to' reply from
- each NET/ROM node in the path. When it finally gets to
- the destination it sounds a chime to alert you that the
- connect has been achieved.
-
- The LAN-LINK.DIR file entry for this path is as follows:
-
- K1HTV ELK v WB4APR-5!SNJ3!NNJ!WMA!SCCT!K1HTV
-
- where the '!' separates each stage of the link.
-
- The key word is K1HTV. LAN-LINK then scans the line to
- see if there is a '!' in it. If there is it knows that
- it is dealing with a NET/ROM path. It then tells the
- TNC to attempt a connect with the characters following
- the key word up to the first '!'. In this case it
- tells the TNC to connect to ELK via WB4APR-5. When the
- TNC sends back the connected message, LAN-LINK tells
- the TNC to try to connect to the next node in the path,
- namely in this example, SNJ3. The sequence continues
- each time a connection is made until the link is
- complete.
-
- To set up a directory entry just use the format shown
- above. Place a '!' sign after the uplink path and
- different node segments. Do not place one after the
- downlink path.
-
- Depending on the configuration, LAN-LINK will issue a
- 'disconnect' command to the TNC in the event the
- NET/ROM or KA-Node connect attempt fails. This feature
- is designed for known paths not for general path determination.
-
- KA-Nodes
-
- You can connect or crossconnect via KA-Nodes using the
- directory file. You must still use the ! separators as
- well as two new symbols % and &. Use % for 'C' and &
- for 'X' in KA-Node links..
-
- For example, given that a path to W9TNN-2 is first to a
- local KA node [JRW] then to a second node on the same
- VHF frequency [W3EAX-7] and lastly via a cross connect
- on 40 Meters to W9TNN-2, the line in the LAN-LINK.DIR
- file would be as follows.
-
- w9tnn-2 jrw!%w3eax-7!&w9tnn-2
-
- You can mix NET/ROM and KA-Node paths as in:
-
- n7dva!g3zcz-9!&WA6IEL-4!n7dva v kl7vz-3
-
- The different symbols are used for the KA node to tell
- LAN-LINK which replies to look for as well as what to
- prefix the call with.
-
- Depending on the Node Drop Link Flag configuration,
- LAN-LINK will issue a 'disconnect' command to the TNC
- in the event the NET/ROM or KA-Node connect attempt
- fails. This feature is designed for known paths not
- for general path determination.
-
- Loop Backs
-
- In the Packet Communications Mode, if you want to loop
- back to yourself through someone else you would have to type
-
- C <yourcall> V <hiscall>.
-
- For example if I (G3ZCZ) wanted to loop back through
- G3RWL, I would have to type the command
-
- C G3ZCZ V G3RWL
-
- to the TNC.
-
- In LAN-LINK you just have to enter the '/' character
- followed by the call of the station you want to loop
- back through. For example if I (G3ZCZ) wanted to loop
- back through G3RWL, I just need to enter
-
- /G3RWL
-
- as the call to connect to at the Alt-C prompt, and
- LAN-LINK will tell the TNC to try to connect to G3ZCZ
- via G3RWL, namely issue the command 'C G3ZCZ V G3RWL'
- to the TNC.
-
- LAN-LINK has special hot keys for connecting to a BBS and packet
- cluster. Try the Alt-Y and Alt-Z keys instead of the Alt-C key.
