Dynamically Setting Geometry

[chengpengvb]

Hello:
I tried to dynamically set terminalWidth and terminalHeight with the following code:

sendNAWS(cols: number, rows: number): void {
        if (!this.socket || !this.socket.writable) {
            this.emit('error', new Error('Socket is not writable'));
            console.error('Socket is not writable. Cannot send NAWS.');
            return;
        }
        const nawsBuffer = Buffer.from([
            255, // IAC
            250, // SB
            31,  // NAWS
            (cols >> 8) & 0xff, // Columns high byte
            cols & 0xff,        // Columns low byte
            (rows >> 8) & 0xff, // Rows high byte
            rows & 0xff,        // Rows low byte
            255, // IAC
            240  // SE
        ]);
        console.log(`Sending NAWS command with cols=${cols}, rows=${rows}:`, nawsBuffer);
        this.socket.write(nawsBuffer, (err?: Error) => {
            if (err) {
                this.emit('error', err);
                console.error('Failed to send NAWS command:', err);
            } else {
                this.emit('geometrySet', { cols, rows });
                console.log(`NAWS command sent successfully for cols=${cols}, rows=${rows}.`);
            }
        });
    }

But it didn't work. Has anyone encountered the same requirement?
