iirc I've had similar issues earlier this year when my protectli arrived.
it must have been something silly like killing the unresponsive cu from another ttyCn and then just reissuing the cu again would suddenly work. Can you give it a try if not already done coincidently?
Don't remember exactly if I killed cu or if ~. to exit the login worked. Just out of memory, hope it helps. On 04.08.25 23:01, Polarian wrote:
Good evening, I have setup OpenBSD over serial on many RPI's in the past, but tonight I have been having a really bad time. I use a ch341 which has worked for me in the past, I have checked my pinout many MANY times, I have tried cu on FreeBSD, and tio on Arch Linux but the same issue keeps occurring. Baud-rate has been set to 115200 OpenBSD side in /etc/boot.conf as it was having issues with the default 9600 (text was gibberish despite both sides being 9600). So serial works, rx is fine I can read the output and I get the login prompt, but tx is not working, I don't think its just openbsd as it doesn't appear to be working in the bootloader either. Its not the biggest deal as I can set the tty to fb0 and use a monitor and keyboard, but carrying around a monitor and keyboard and copying text over from my laptop is not ideal. I believe my adapter could potentially be broken, as like I said its worked flawlessly in the past. Just in case I have made a stupid mistake I am posting here, if anyone has any suggestions let me know. Apologies for the noise. Take care,
