Serial Communication Toolbox for Scilab doesn’t load automatically. I have the latest versions, 2024 and 2025, installed. Version 2024 loads automatically, but version 2025 doesn’t; it works if you load it manually. I’m not sure if it’s a problem with my computer. Could you give me some guidance?

Hello,

The serial toolbox can be installed in Scilab 2025.1:

```auto
--> atomsInstall serial
Generating loader.sce...
Generating unloader.sce...
Generating cleaner.sce...
Building macros...
-- Creation of [seriallib] (Macros) --
genlib: Processing file: openserial.sci
Building help...

Starting the Serial Toolbox
	Load macros
	Load help
Building the manual file [javaHelp] in C:\Users\steph\AppData\Roaming\Scilab\scilab-2025.1.0\atoms\x64\serial\0.5\help\en_US.

 ans = [1x5 string]

  "serial" "0.5" "user" "SCIHOME\atoms\x64\serial\0.5" "I"

```

It is compiled on-the-fly, but that should not make any difference for you, right ? Then the toolbox will be automatically loaded when Scilab starts.

S.
