Serial Bandwidth Monitor 3.4 -
Beyond standard Windows network adapters, version 3.4 interfaces directly with hardware abstractions using protocol-specific parsing drivers. It records, translates, and measures bandwidth constraints across the following transport mediums:
Bandwidth Monitor (v3.4.0.757) by BWMONITOR.COM is a freeware tool that tracks network traffic, optimizes performance, and monitors data usage. Released in 2016, this application provides real-time monitoring and historical logs to assist users in managing bandwidth consumption.

If you require more advanced protocol analysis or specific COM port monitoring, consider these alternatives:
In many scenarios, simply knowing that a device is "connected" is not enough. You need to know if it is communicating efficiently.
: This specific feature allows users to monitor and control the status of RS232 control lines, such as DTR (Data Terminal Ready) and RTS (Request to Send). Protocol Support Serial bandwidth monitor 3.4
Reports can be exported into various formats, such as .txt , .csv , and .html , for analysis in external applications like Microsoft Excel or for publication on internal web servers, allowing for reporting to stakeholders. 4. Bandwidth Usage Notification
: Displays live download and upload speeds in both graphical and numerical formats. Usage Logging
: Choose the active COM or tty port from the dropdown device list.

This is a network utility designed to track internet and LAN data usage. Real-Time Monitoring
CPU usage spikes on high-speed links (e.g., 921600 baud). Solution: In version 3.4, go to Settings > Performance and reduce the graph refresh rate from 20ms to 100ms. Also enable “Kernel Buffering” to reduce user-mode transitions.
is utilized for its script-based parsing and packet-level inspection. Data Capture : Using the
They are often used in several ways:
For encrypted or complex protocols, run Serial Bandwidth Monitor 3.4 alongside Wireshark’s serial capture feature. Use the timestamp sync feature (available in the Tools > Sync Timestamps menu) to correlate bandwidth spikes with specific packet types.
Serial Bandwidth Monitor 3.4 is a lightweight, real-time utility designed for engineers and developers monitoring data throughput on COM ports. This version provides precise, low-latency tracking of incoming and outgoing data, allowing for immediate identification of bottlenecks or transmission errors in industrial, automation, and embedded systems. Key Features (Version 3.4) Real-time Throughput Tracking:
Modern systems often use USB-to-Serial adapters or purely virtual COM ports to connect software applications. Version 3.4 monitors these virtual pipes to ensure that software drivers are not introducing artificial lag or processing bottlenecks. How to Optimize Serial Performance with Version 3.4
