Locate the dropdown menu and select your active COM port.
If the app fails to detect your USB-to-TTL drivers, right-click the executable and select Run as Administrator . Configuring the Serial Connection
Open Windows Device Manager. Check for a yellow exclamation mark under "Ports (COM & LPT)". Download and reinstall the official driver for your specific chip (e.g., WCH CH340 drivers or Silicon Labs CP210x drivers). 2. Received Data Appears as Random Symbols or Gibberish

Ensure no other software (like Arduino IDE, Cura, or another terminal) is currently using the port. Try unplugging and re-inserting your USB cable.
Enhanced advanced packet wrapping, allowing users to exclude frame headers and trailers from automatic checksum calculations. Step-by-Step Guide: Setting Up the English Interface

Debugging an embedded device requires meticulous configuration of hardware parameters. Misaligned boundaries cause incoming strings to distort into unrecognizable corruption.
The "V5.13.1" version brought a critical improvement that distinguishes it from earlier tools: . A common frustration with older serial debug tools was that the application would freeze or crash if a USB-to-serial adapter was accidentally unplugged while the port was open. Sscom V5.13.1 fixes this issue, ensuring that most USB chips (excluding PL2303) can be reinserted and the connection will automatically recover without needing to restart the application. Furthermore, it boasts a smooth display engine that minimizes the risk of data loss, even at high baud rates, and correctly displays Chinese or other UTF-8 characters without garbled text.
: This is a classic baud rate mismatch. Ensure the baud rate in Sscom exactly matches the Serial.begin(speed) rate defined in your firmware. Check for a yellow exclamation mark under "Ports
| Capability | What It Does | Practical Benefits | |------------|--------------|--------------------| | | Assign individual settings (baud rate, parity, data bits, stop bits, flow control) for each open COM port. | No need to close one session to re‑configure another—perfect for testing devices with different protocols. | | Live Data Merging Window | Drag‑and‑drop any open port into a “merge window” where incoming bytes from all selected ports are displayed together, each prefixed with a configurable port identifier. | Instantly spot timing relationships, cross‑device communication patterns, or protocol collisions. | | Per‑Port Hex/ASCII Toggle | Switch any port’s view between pure ASCII, pure hexadecimal, or a split hex/ASCII mode. | Quickly decode human‑readable messages while still being able to inspect raw byte values. | | Real‑Time Logging with Timestamp Granularity | Enable logging per port or for the merged view. Each line can include: • Date + time (down to milliseconds) • Port ID • Direction flag (RX/TX) • Optional custom tag | Generates ready‑to‑import logs for Excel, MATLAB, or custom parsers. Millisecond timestamps are essential for debugging time‑critical embedded protocols. | | Dynamic File Capture & Replay | Capture traffic to a file on‑the‑fly (auto‑rotate when a size limit is reached). Later, load the capture and replay it on any selected port at original timing or at a user‑defined speed factor. | Perfect for regression testing: record a successful session once, then replay it repeatedly to verify firmware changes. | | Conditional Triggers & Auto‑Responses | Define simple trigger rules (e.g., “when the string ‘ERROR’ appears on COM3, send ‘RESET\r\n’ on COM5”). Supports regex patterns and multi‑byte binary sequences. | Automates repetitive diagnostic steps and reduces manual intervention during long‑run tests. | | Port‑Specific Macro Recorder | Record a sequence of keystrokes or command strings for a given port, save it as a macro, and bind it to a toolbar button or hotkey. | One‑click execution of complex command sequences (e.g., bootloader entry, firmware upgrade commands). | | Graphical Signal Analyzer (Optional Plug‑in) | For ports that carry binary waveform data (e.g., UART‑based sensor streams), the built‑in analyzer can plot voltage‑level equivalents, frequency spectra, or custom charts based on user‑defined parsing scripts (Python/JavaScript). | Turns raw serial data into visual insights without needing external oscilloscopes. |
