Seriport – Professional Serial Port Terminal Seriport is a professional COM port terminal application designed to make serial communication fast, reliable, and comfortable. It provides all the necessary tools in a single window for industrial device development, Arduino/ESP32 debugging, Modbus analysis, RS-232/485 protocol testing, and simulation of application-specific protocols. ───────────────────────────────────────── ? CONNECTION AND PORT MANAGEMENT ───────────────────────────────────────── • Automatically detects COM ports; the list updates instantly when a device is connected. • Baud rates from 300 to 3,000,000 can be selected from the list or entered manually (supports non-standard values such as 250,000 bps). • Fully configurable: Parity (None/Odd/Even/Mark/Space), Data Bits (5–8), Stop Bits (0/1/1.5/2), and Handshaking (None/RTS–CTS/XOn–XOff/Both). • One-click Preset options for common combinations such as 8N1, 7E1, 7O1. • DTR, RTS, and BREAK signals can be managed in real time from the advanced modem control panel. ───────────────────────────────────────── ? TERMINAL AND DATA DISPLAY ───────────────────────────────────────── • Received data is displayed in the terminal in real time. • Eight display formats: Text, Hex, Binary, Decimal, ASCII, Hex-Dump, and ALL mode that shows all formats side by side. • Timestamp feature adds [SS:dd:ss.fff] before each line; makes it easy to track event sequence in long sessions. • Auto-scroll: new data moves the terminal to the bottom; temporarily pauses when reviewing history. • CR/LF/TAB characters can be displayed as visual symbols in classic terminal style. • Terminal output width adjustable between 20–120 characters with horizontal scrolling; supports classic Daktilo Mode (Classic CR Overwrite) where CR returns the cursor to the beginning of the line. • Customizable font family, size, and color (14 color options + theme default). • Terminal content can be exported to .txt or .csv file. ───────────────────────────────────────── ? MULTI-FORMAT DATA TRANSMISSION ───────────────────────────────────────── • Send data in TEXT, HEX, BINARY, DECIMAL, and ASCII formats. – HEX: bytes separated by spaces, dashes, or 0x prefix (e.g., "AA 55 FF" or "0xAA-0x55"). – BINARY: 8-bit groups, supports 0b prefix (missing bits are automatically padded). – DECIMAL: values 0–255 separated by spaces or commas. – ASCII: 7-bit ASCII output for users who want to avoid special characters. • Line ending (None / LF / CRLF / CR) selectable per transmission. • Transmission history is stored in a dropdown list; previous commands can be recalled with one click. • Repeat transmission: adjustable repeat count or continuous mode with interval in milliseconds. • Hex preview of bytes is visible in the status bar before sending. ───────────────────────────────────────── ? TRANSMISSION FROM FILE ───────────────────────────────────────── • Send large data loads directly from file, such as long AT command sequences, Modbus RTU frame lists, or binary blocks. • Source format (file content) and target format (port transmission format) can be selected independently. • Adjustable inter-line delay (ms) prevents buffer overflow on the receiving side. • Loop mode: automatically returns to the beginning when the end of the file is reached. • Empty lines are skipped; lines starting with # or ; are treated as comments. • Status bar shows progress and number of transmitted lines in real time; Stop button allows interruption at any time. ───────────────────────────────────────── ? MACROS / AUTOMATIC RESPONSE ENGINE ───────────────────────────────────────── • When a received line matches a user-defined regex pattern, the specified response is automatically sent. • Full support for .NET regex syntax; capture groups can be used in the response text as $1, $2 (e.g., ^ECHO:(.+)$ → ECHO:$1). • Case-insensitive matching can be enabled or disabled per rule. • Macros are automatically saved to %AppData%\Seriport\Macros.json and reloaded on application startup. • All rules can be enabled or disabled with a single checkbox. • Practical built-in examples such as Ping-Pong, Echo, and status query responses are included. ───────────────────────────────────────── ? STATUS LEDS AND SIGNAL MONITORING ───────────────────────────────────────── • Colored status LEDs for Connection, TXD, RXD, CTS, DSR, CD, Ring, BREAK, and Error. • Connection LED shows port status in green/orange/red. • TXD and RXD LEDs flash briefly with each byte sent or received. • Error LED visually reports framing, parity, overrun, rx-over, and tx-full errors. ───────────────────────────────────────── ⚙️ SETTINGS AND PERSONALIZATION ───────────────────────────────────────── • Support for dark and light themes; preferences are saved to %AppData%\Seriport\appsettings.json. • 24 interface languages: Turkish, English, German, French, Spanish, Italian, Portuguese, Russian, Chinese, Japanese, Korean, Arabic, Hindi, Dutch, Swedish, Norwegian, Danish, Finnish, Polish, Czech, Hungarian, Indonesian, Thai, Vietnamese. • Configurable default line ending, timestamp, and transmission confirmation preferences. • All settings are automatically saved immediately upon change; no “Save” button required. • Ctrl+, for quick access to Settings, F1 for quick access to Help. ───────────────────────────────────────── ? COMPREHENSIVE HELP AND FAQ ───────────────────────────────────────── • Built-in Help tab containing sections: Quick Start, Connection Settings, Transmission Formats, Macros, File Transmission, Terminal Usage, Keyboard Shortcuts, and Frequently Asked Questions. • All help content automatically adapts to the selected interface language. ───────────────────────────────────────── ? PRIVACY AND SECURITY ───────────────────────────────────────── • Seriport requires no internet connection and uses none. • No user data is sent to the cloud. • All settings are stored only locally in the AppData folder. • The application only accesses the serial port that the user actively selects.
