TestRS232 (En) is a lightweight utility for verifying and troubleshooting RS‑232 serial connections. It helps technicians, engineers, and hobbyists open a COM port, configure communication parameters, and send or monitor data in real time—ideal for diagnosing cable issues, validating device firmware, or running loopback tests.

Key features:

Quick scan and selection of available COM/serial ports
Configurable baud rate, data bits, parity, stop bits, and flow control
Send and receive data in ASCII or hexadecimal views
Loopback and manual transmit tests for fast diagnostics
Optional logging with timestamps for documentation and analysis
Status display of modem/control lines (RTS/CTS, DTR/DSR, DCD, RI) when supported by your adapter
Works with built‑in RS‑232 ports, add‑in cards, and most USB‑to‑serial adapters

Typical workflow:

Connect your RS‑232 device or loopback plug
Select the correct COM port and matching serial settings
Open the port, transmit test data, and monitor responses
Save logs as needed for troubleshooting or reports
