(v0.8 and above) The serial multiplexer is an optional eLua component that allows using several serial ports over a single physical serial link connection. It can be a very convenient feature, since some eLua components (such as or ) need a serial link to the PC and it’s very incovenient (or even impossible sometimes) to connect the eLua board to the PC with 2 or more serial cables. A common use scenario for the serial multiplexer is to have the eLua shell and RFS running over a single physical connection to the PC, a very convenient method that will probably appeal to most eLua users.

Linux already supports the virtual serial port mechanism described above via the standard UNIX pseudo terminals, see for details. Note that the multiplexer supports only BSD PTYs ( dev/ttypx) and not Unix98 PTYs ( /dev/ptmx). They are quite standard (although they are becoming obsolete in some Linux distributions) so you shouldn’t have any problems with them. A quick check for BSD PTYs is to look in your /dev directory for ttypx and ptypx files. If they aren’t there, you need to enable support for BSD PTYs in your system. How to do this is OS dependent and beyond the scope of this tutorial, so google is your friend. For an example on how to enable them in Ubuntu check.
