Later we will go deeper in more special cases. 1.2 The first steps In the following I will introduce luactb with some small examples so you will get a feeling for the usage and - of course - the chances luactb will offer you for your own applications.

Just download the archive file, unpack it in any directory and you are ready to start. For updates and news take a look at: There are no further requirements. 1.1 Where can I get the newest luactb luactb is free software and available from the IFTOOLS website. By the use of the iftools library luactb allows you to search and list all available serial ports, accessing virtual serial ports simply by passing one or more of the USB specific informations (don t worry about changing COM port numbers), sending Modbus RTU or ASCII sequences with automatically generated checksums and a lot more. And all this comes as a single executable for Linux or Windows with a size less than 1 MByte. For this, luactb integrates the iftools library and adds a lot of useful extensions for Modbus, time measuring and keyboard query (kbhit). It comnes with built-in functions to make the communication with RS232/RS485 devices as easy as possible. luactb is a stand alone Lua interpreter based on the Lua sources of version (see Lua license and copyright).

This chapter shows you how to use the Luactb shell to communicate interactively with a serial device and run scripts automatically. Luactb combines the facilities of the iftools library with the amazing script language of Lua. A scripting language will offer you a lot of benefits in case of periodical or repetitive tests.
