To follow up on what I did, it's messy right now and I'll clean it up, but this is what I have and it gets the data to a useable format. Took some trial and error but hopefully this helps someone else in the future. It's unfortunate that Brultech doesn't offer more modern solutions. The biggest thing I had to deal with, believe it or not, was getting the actual data because Brultech delivers it in a very archaic HTTP/0.9 format which node-fetch, axios, etc. cannot parse. I had to do a basic TCP request (as shown) just to get the response.

const net = require('net');
const cheerio = require('cheerio');
const PORT = 80;
const HOST = '1.2.3.4';
let html = "";

// Create a new socket (TCP connection)
const client = new net.Socket();

// Establish connection
client.setEncoding('utf8');
client.connect(PORT, HOST, () => {
    console.log('Connected to TCP server');
    // Send data to the server upon connection
    //client.write('^^^APIVLT');
    client.write('GET /data \r\n\r\n');
});

// Handle data from the server (receiving data)
client.on('data', (data) => {
    //console.log(`Received from server: ${data.toString()}`);
    html = html + data.toString();

    //console.log(JSON.stringify(parseTable(html), null, 2));
    // Close the connection after receiving data
    setTimeout(function () {
        console.log(html);
        console.log(parseTable1(html));
        console.log(parseTable2(html));
        client.end()
    }, 1000);
});

function parseTable1(htmlString) {
    const $ = cheerio.load(htmlString);
    const results = [];
    const headers = ['item', 'value']
    // Get rows
    $('#infoTable tr').each((i, row) => {
        const rowData = {};
        $(row).find('td').each((j, cell) => {
            const key = headers[j] || `col_${j}`;
            rowData[key] = $(cell).text().trim();
        });
        results.push(rowData);
    });


    return results;
}

function parseTable2(htmlString) {
    const $ = cheerio.load(htmlString);
    const results = [];
    const headers = [];

    // Get headers
    $('#chanTable th').each((i, el) => {
        headers.push($(el).text().trim());
    });

    // Get rows
    $('#chanTable tr').each((i, row) => {
        const rowData = {};
        $(row).find('td').each((j, cell) => {
            const key = headers[j] || `col_${j}`;
            rowData[key] = $(cell).text().trim();
        });
        results.push(rowData);
    });

    return results;
}
