Unlike generic software, you cannot find the latest version on GitHub. The official source is the or your module distributor’s support portal. As of 2025, the most common versions are:

The SIMCom Serial Port Tool is a that excels at:

The (often labeled as SIMCOM_Serial_Tool.exe or included in packages like SIM800_Series_Serial_Tool ) is a Windows-based graphical application specifically tailored for SIMCOM cellular modules. While generic serial tools like PuTTY or Arduino Serial Monitor work for basic AT commands, the SIMCOM tool offers proprietary features: simcom serial port tool

Functionality is often organized into tabs for specific tasks like SMS, GNSS (GPS), TCP/UDP networking, and HTTPS .

Here are some tips and tricks to help you get the most out of the SIMCom serial port tool: Unlike generic software, you cannot find the latest

(like an FTDI board) and a stable 5V or 3.7V power supply, as these modules are notorious for power spikes during network registration. Standard Settings : Most modules default to 115200 baud , 8 data bits, no parity, and 1 stop bit (8N1). The "Handshake" and receiving an

A "deep" look at serial communication reveals that physical wiring is only half the battle. SIMCom modules act as , requiring careful management of Hardware Flow Control (RTS/CTS) to prevent data loss during heavy transmissions. While generic serial tools like PuTTY or Arduino

The tool is tailored for cellular engineering and includes several advanced features not typically found in generic serial monitors:
