Thread-based communication

CleverTerm provides a GUI independent device access. The transmission speed only relies on the OS and the device itself and guarantees maximum rates. A stop watch displays the sending time and lets you validate transfer durations.

Hardware support

CleverTerm works with all kind of serial ports and USB to RS232/RS485 converters which are supported by your OS. Depending on the device it provides baud rates from 1 to 1MBaud and static mark and space parities.

The program shows all line states, let you toggle the RTS and DTR signals and counts all occuring frame, parity, break and overrun conditions.

Build your own sending dialogs

A unique feature of the CleverTerm program is the option to extend its functionality by own sending dialogs. These range from simple inputs like to generate telegrams with individual checksums to a complete simulation of Modbus master requests. The dialogs are easily written in Lua.

Comes with a powerful script editor

with just in-time dialog/script execution.

Save your changes and your dialog will be updated immediately. As simple as it is, it makes the design of a new dialog an amazing experience.

And the editor is not only especially designed for writing Lua code, it features also all kind of qualities you expect from a good editor like code folding, syntax highlighting, multi-doc interface, unlimited undo/redo and more.

Comfortable input modes

let you enter und edit sending byte sequences as best as it fits your intention. CleverTerm offers data input in ASCII, HEX or mixed. A history function makes it easy to edit and/or repeat a former byte sentence.

Integrated Modbus ASCII and RTU support

The CleverTerm uses its own expendability to simulate all master request telegrams for Modbus ASCII and RTU.

Instead of building a valid Modbus byte sequence by hand (including calculating the right checksum), you just select the function number in the Modbus dialog and input the device address and the according function parameter.

The Modbus dialog is especially useful when testing Modbus devices.
