You can watch the progress of the connection (if you have connect debugging enabled [set/debug connect]) on the cluster.pl screen and you should see something like this:- @@ -103,21 +112,21 @@ Last modified: Tue Apr 10 00:21:34 BST 2001 <- D G1TLH connect gb7djk-1 -> D G1TLH connection to GB7DJK-1 started -> D G1TLH G1TLH de GB7DJK 13-Dec-1998 2046Z > - timeout set to 15 - CONNECT sort: telnet command: dirkl.tobit.co.uk + timeout set to 15 + CONNECT sort: telnet command: dirkl.tobit.co.uk CHAT "login" -> "gb7djk" received " Red Hat Linux release 5.1 (Manhattan) Kernel 2.0.35 on an i586 " - received "login: " - sent "gb7djk" + received "login: " + sent "gb7djk" CHAT "word" -> "gb7djk" received "gb7djk " - received "Password: " - sent "gb7djk" + received "Password: " + sent "gb7djk" Connected to GB7DJK-1, starting normal protocol <- O GB7DJK-1 telnet -> B GB7DJK-1 0 @@ -128,7 +137,34 @@ Last modified: Tue Apr 10 00:21:34 BST 2001 <- D GB7DJK-1 PC18^ 1 nodes, 0 local / 1 total users Max users 0 Uptime 0 00:00^5447^~ etc - + +

I have coloured the commands in an attempt to make it clear as to what goes on, where and why. + These coloured lines are miscellaneous commands, the things + that are this colour are the strings I am looking for (what I am "expecting") + and the things that are this colour + are the commands I am going to make when I see the "expect" strings in the input.

+ +

The script starts by setting the timeout to 15 seconds, then starts + the connection. It is important to note that, in the case of + an ax25 connection (usually) this will be the callsign of the first hop along the + route that you are going to take to the destination, so this will be typically the callsign + of your local node.

+ +

You will notice that the script waits until it sees the left hand string + of the pair and only then does it send the, + string on the right + hand side. This is called a State Machine.

+ +

A state machine "walks" through a conversation (in this case) looking + for "states" (in this case particular strings) and then performs some + "action" (usually some kind of connect command for the type of system + you are trying to navigate). When one "state" "fires" (detects the string + are looking for), it sends the command associated with that state and then + moves onto the next "state", in our case: the next line.

+ +

PLEASE NOTE: the colouration in the above example is for illustrative purposes + only, the debug output is all one colour.
