Deno.stdin raw map?

Does anyone have a map to which key is what raw buffer gotten from Deno.stdin? Like i can just search in a map, what key 27 represents? Also, i cant use stdin.setRaw(false) Code:

const stdin = Deno.stdin;
stdin.setRaw(true, {cbreak: Deno.build.os !== "windows"});

const maxBuffer = new Uint8Array(1024);
const read = async () => {
    const size = await stdin.read(maxBuffer);
    const buffer = maxBuffer.subarray(0, size || 0).toString();

    Deno.writeTextFileSync("buffer.txt", buffer + "\n", {append: true});

    setTimeout(read, 1000 / 60);
};

read();

Kill Deno.Command

Is it possible to kill/end a Deno.command-instance? Example code:

(async () => {
    let ffmpegProcess: Promise<Deno.CommandOutput> | undefined;
    ffmpegProcess = new Deno.Command("ffmpeg", {args: ["-i", filename, `${folder}/frame%08d.png`, "-threads", "1"]}).output();
    await ffmpegProcess;
    done = true;
})();

// Later some time
ffmpegProcess.close(); // Something like that?

    let ffmpegProcess: Promise<Deno.CommandOutput> | undefined;
    ffmpegProcess = new Deno.Command("ffmpeg", {args: ["-i", filename, `${folder}/frame%08d.png`, "-threads", "1"]}).output();
    await ffmpegProcess;
    done = true;

Sending proper Content-Type depending on file sent

Hello. Im new to Deno and TypeScript and i wanted to convert one of my older projects (NodeJs and JavaScript). Now, my plan is to send the requested file, which actually does work, but the response doesnt send the proper content-type. What do i have to do in order to get this working properly?

const handler = async (req: Request): Promise<Response> => {
    const url = new URL(req.url);

    const filePath: string = "./client" + (url.pathname === "/" ? "/index.html" : url.pathname);

    try {
        const file = await Deno.open(filePath, {read: true});
        const readableStream = file.readable;
        
        return new Response(readableStream, {
            status: 200,
        })
    } catch (_error) {
        return new Response(`GET ${filePath}`, {status: 404});
    }
};
