How to build

Use SimpleCom.sln on your Visual Studio.
I confirmed x64 build on VS 2019.

Distribution package

You can get distribution package when you do release build.

• dist: ZIP archive
• Installer: MSI installer

MSI installer installes SimpleCom.exe and README.md (and also custom action assembly). It will deploy JSON fragment for SimpleCom into %ProgramData% or %LocalAppData% (it depends on install user choice). So the use can use SimpleCom without any configuration (as following) on Windows Terminal.

How to use on Windows Terminal

You can use fragments.json to add SimpleCom to your Windows Terminal.
For example, run following commands to add SimpleCom for all users.

PS > mkdir "C:\ProgramData\Microsoft\Windows Terminal\Fragments\SimpleCom"
PS > cp C:\Path\To\fragment.json "C:\ProgramData\Microsoft\Windows Terminal\Fragments\SimpleCom"

Please see Applications installed from the web in Microsoft Docs.

Notes

• SimpleCom sends / receives VT100 escape sequences. So the serial device to connect via SimpleCom needs to support VT100 or compatible shell.
• F1 key is hooked by SimpleCom, so escase sequence of F1 (ESC O P) would not be propagated.
• SimpleCom supports ANSI chars only, so it would not work if multibyte chars (e.g. CJK chars) are given.
• Run resize provided by xterm if you want to align VT size of Linux box with your console window.
