Can anyone help me out here please? I hav a Linbpq up and running and try to add ZORK to the Application via a Startscript. This won't work, and I dont know where is my Problem? APPLICATION 3,ZORK,/usr/local/bin/ZORK.Start.sh It doesent matter what I do in the Script, bbq won't even try to start it. ZORK appears in the manue of possible Application if i connect via Telnet. If I try to start ZORK, I get the Error Invalid command - Enter ? for command list have anyone a clue where is my problem and how to solve it please? 73 Tom

It's actually simple once you understand how to do it.
in bpq32.cfg, look at your telnet server section (here's mine):

    PORT
    PORTNUM=1
    ID=Telnet Server
    DRIVER=Telnet
    CONFIG
        LOGGING=1
        CMS=1
        HTTPPORT=8080
        TCPPORT=23
        FBBPORT=8010
        USER=M0ODZ,PASSWORD,M0ODZ,,SYSOP
        DISCONNECTONCLOSE=1
        CMDPORT 63000 63001
    CTEXT=Welcome to GB7ODZ Telnet Server\n Enter  ?  for list of commands\n\n
ENDPORT

In the APPLICATIONS section:

APPLICATION 4,HELLO,C 1 HOST 0 K S,YOURNODECALL-4,YOURAPPSHORTNAME,255

replacing YOURNODECALL with your node call eg. M0QRZ and YOURAPPSHORTNAME with a snappier version of the appname a remote user can connect directly to eg. QRZHLO, so a remote user can connect directly to QRZHLO and they will be served with the app. For Example:

APPLICATION 4,HELLO,C 1 HOST 0 K S,M0QRZ-4,QRZHLO,255

Do you see the CMDPORT line? That is where the magic happens. The number that follows is a port number on the BPQ32 computer that an app listens to.

install node and npm:

sudo apt install nodejs npm

write a .js file to create a server on one of the ports listed in CMDLINE eg 63000.

/**
 * Simple Packet Radio "Hello World" Server
 * Runs on Port 63000
 */

const net = require('net');
const SERVERADDRESS='127.0.0.1';
const PORT = 63000;
const MESSAGE = "Hello packet radio world!\r\n";

const server = net.createServer((socket) => {
    // Log connection to the screen
    console.log(`Connection received from: ${socket.remoteAddress}`);

    // Send the message
    socket.write(MESSAGE);

    // Give it a tiny delay to ensure the packet is buffered 
    // through the LinBPQ stack before closing
    setTimeout(() => {
        socket.end();
    }, 500);
});

server.on('error', (err) => {
    console.error(`Server error: ${err.message}`);
});

server.listen(PORT, SERVERADDRESS, () => {
    console.log(`Packet App listening on ${SERVERADDRESS}:${PORT}`);
});

Save this as sampleserver.js
run

node sampleserver.js

in a new window, type

telnet SERVERADDRESS PORT

eg.

telnet 127.0.0.1 63000

And you should see Hello packet radio world! displayed on your screen.

For your real world situation (playing Zork, much respect!):

PORT
    PORTNUM=1
    ID=Telnet Server
    DRIVER=Telnet
    CONFIG
        LOGGING=1
        CMS=1
        HTTPPORT=8080
        TCPPORT=23
        FBBPORT=8010
        USER=M0ODZ,PASSWORD,M0ODZ,,SYSOP
        DISCONNECTONCLOSE=1
        CMDPORT 63000 63001
    CTEXT=Welcome to GB7ODZ Telnet Server\n Enter  ?  for list of commands\n\n
ENDPORT

APPLICATION 4,ZORK1,C 1 HOST 0 K S,M0QRZ-4,QRZZ1,255 ; CMDPORT first number (starting counting at 0) 63000
APPLICATION 5,ZORK2,C 1 HOST 1 K S,M0QRZ-4,QRZZ2,255 ; CMDPORT second number 63001

If you look carefully you will notice C 1 HOST 0 K S and C 1 HOST 1 K S. 0 is the first number in the CMDPORT list, 1 is the second and so on.

Here is a real world script to run Zork:

/**
 * Zork1.z5 Packet Radio Wrapper
 * * This script:
 * 1. Listens on Port 63000
 * 2. Asks for a Callsign (if not automatically provided by BPQ)
 * 3. Creates a unique directory for that Callsign
 * 4. Launches 'frotz' inside that directory
 */

const net = require('net');
const { spawn } = require('child_process');
const fs = require('fs');
const path = require('path');

const PORT = 63000;
const GAMES_DIR = path.join(__dirname, 'player_data');

// Ensure the base games directory exists
if (!fs.existsSync(GAMES_DIR)) {
    fs.mkdirSync(GAMES_DIR);
}

const server = net.createServer((socket) => {
    socket.write("--- Welcome to the Zork 1 Packet Portal ---\r\n");
    socket.write("Please enter your Callsign: ");

    let callsign = "";

    socket.on('data', (data) => {
        // If we haven't got the callsign yet, treat the first input as the ID
        if (!callsign) {
            callsign = data.toString().trim().toUpperCase().replace(/[^A-Z0-9-]/g, '');
            
            if (callsign.length < 3) {
                socket.write("\r\nInvalid Callsign. Please try again: ");
                callsign = "";
                return;
            }
            socket.write(`\r\nWelcome ${callsign}\r\n\r\n`);

            setupGame(socket, callsign);
        }
    });
});

function setupGame(socket, userCall) {
    const userDir = path.join(GAMES_DIR, `SAVEDIR_${userCall}`);

    // Create user-specific directory for save files
    if (fs.existsSync(userDir)) {
        socket.write(`\r\nWelcome back, ${userCall}!\r\n`);
    }
    else
    {
        fs.mkdirSync(userDir);
        socket.write(`\r\nWelcome, ${userCall}!\r\n\r\n`);
    }
    socket.write("Loading Zork 1...\r\n\r\n");

    // Start frotz
    // -p: plain text mode (better for packet/telnet)
    const frotz = spawn('frotz', ['-p', '/usr/share/games/zork1.z5'], {
        cwd: userDir
    });

    // Pipe socket to frotz stdin
    socket.pipe(frotz.stdin);

    // Pipe frotz stdout back to socket
    frotz.stdout.on('data', (data) => {
        // Replace Unix newlines with Telnet/Packet friendly CRLF
        socket.write(data.toString().replace(/\n/g, '\r\n'));
    });

    frotz.stderr.on('data', (data) => {
        console.error(`Frotz Error: ${data}`);
    });

    frotz.on('close', (code) => {
        socket.write("\r\n[Zork Session Closed - I blame the Grue!]\r\n");
        socket.end();
    });

    socket.on('close', () => {
        frotz.kill();
    });
}

server.listen(PORT, '0.0.0.0', () => {
    console.log(`Zork 1 Server listening on port ${PORT}`);
});

Save this as zork1server.js
run
node zork1server.js

To make it permanent:

sudo npm install -g pm2

# Start your script
pm2 start zork1server.js --name "zork-node"

# Make it start on boot
pm2 startup
pm2 save

Pretty soon, you'll outgrow 1 app, 1 port and make a menu script so all the apps run on the same port.
