New serial terminal WEB to test

Post by cicciocb »

Hi all,
just for testing I developed a little Serial port terminal emulator compatible VT100 that runs inside a web browser.

It can be used directly from the web at this link [Local Link Removed for Guests]

It runs on Windows and Linux but only inside Chrome, Edge or Opera (Firefox do not exposes the API for the WEBserial).

Let me know if you find it interesting, in this case I'll integrate in the new releases of Annex.

P.S.
as it is VT100 compatible, can be used also for other stuff, such as the picomite or other projects that require a VT100 terminal emulation.

Hi, it does sound like something useful. Especially if it can support 74880 baud ;)
Is the main advantage VT100? I'm "old school" and often use VT100 because it supports colour and position via ESC codes.
I'll have play and get back to you. (shame about Firefox)

Edit:
Just had a very quick play.
Naturally, it does not work in Firefox but works fine in Edge & Chrome.
And... yippee... it also works with 74880 baud so now we can see the boot message.
Gets my vote for that alone. :D

The advantage is that it runs inside a web browser without any installation. I plan to exploit this Idea in the future for other tools.

Hi,
Runs without Problems here in Edge.
Like the Idea, even its not can using in Firefox.
Maybe a inputbox for sending chars over the serial is usefull also.

Nice!
But it's a shame web serial is not supported on the Android versions of Chrome,
as there is also a new EspTool-js available - and was hoping to use an Android
tablet for most related things.

It looks that FIrefox will not never support the WEBserial, mainly for security reasons :

I recognize that this functionality could be a little bit risky, even of the access must be explicitly by the user clicking and selecting the serial port.

Thanks for the info, I was not aware of ESPtool.js, this opens a new way to flash devices from the web without any local installation; I'll do some experiments and see what can be done.

About Android, probably it will be available in the future

Molto utile per il debug!
Funziona anche salvando il semplice file html in locale

Very usefull for debug!
It works also from a simple local htm file
