might be a dinosaur, but I'd love to see if there's a web gui for USB serial / RS-232 connection and some logging feature. It's quite helpful for monitoring linux kernel logs in case of a system crash due to some fatal driver crash and/or memory fault.
(Yes, i've experienced both before, and i had to use on RS-232 to confirm cuz otherwise i can't get dmesg out from a crashed computer)
You can buy a USB-to-ttl with a ch341 chip(Or others), plug it into the USB-A port, connect it to the computer serial port, and then enter commands in the web terminal to connect to the serial port minicom -D /dev/ttyUSB0 -b 115200
That's really helpful to know. This is a need that I have, as well. Will this work through a USB hub, for instance, if I wanted to view the serial console on a device that uses the GL-ATX board? Also, it would be really nice if the GLKVM web app (and desktop apps) had a web terminal, maybe under "Toolbox". This would make it similar to how some hypervisors and cloud providers provide access and would make the GLKVM suitable for serial-only devices, such as network equipment and IoT devices.
I just think... If you buy an $80 device just to connect to a serial port, it feels particularly luxurious. I doubt if this is a real usage scenario?
It should be possible to connect to the USB HUB. At least I haven't encountered any problems so far
Yes, connect a USB hub then you can add a USB to serial debug tool to view the serial console.
May I ask you why you want to connect like that?
I have a headless Linux server that I use the serial console for access in case the networking is down. Using the GLKVM, I will be able to remotely control the power using the ATX board and access the serial device console. At the same time, I can use the mass storage to reimage the machine, if needed.
I purchased 3 Comets. I will use one for the headless server, one for a Windows laptop, and one for a MacBook Pro. My primary workstation is a Linux laptop. With this new setup, I won't have to shuffle which laptop is connected to my monitors. I can use them all with a common interface.
Lastly, if the Linux server has a problem, I can ssh to the GLKVM and access the serial console which is much nicer than bouncing through a webpage since it provides a direct text terminal.
Being able to remotely control power, transfer files, and access a serial console is a very attractive use case for me.
