serialTerminal.com VS LibSerialPort.jl

I was really trying to keep it minimalist. On github there is a 150 line version for all the CSS, JS and HTML. https://github.com/Autodrop3d/serialTerminal.com/blob/main/index-150lines.html

A nice serial terminal in the browser that will save you the effort of building one yourself. It’s fairly centered around text passing, so might be useful for just testing connections, or sending commands to a device. I found it on hackaday, and the author mentioned they use it with 3D printers, which is pretty interesting, can imagine plugging in a printer directly to a website and getting a nice printout of something.

Not sure. Julia normally implements single-threaded asynchronous I/O via the libuv C library, however LibSerialPorts.jl doesn't use libuv, and instead uses blocking function calls to the C library libserialports. What might work is if different Julia threads talk to different ports, though I've not tested this. What might not work yet is if different Julia threads try to simultaneously send to the same port, or try to simultaneously receive from the same block. (Locks would have to be added, see https://github.com/JuliaIO/LibSerialPort.jl/issues/69 )
