Hello, all. I send a patch to make coreboot output console using system beeper and a corresponding code to interpret those beeps. I publish it under GPLv2+ but other licensing arrangements are possible. This was very useful to get console on X201 where I have neither serial nor EHCI debug.

This would need some improvements as currently it sometimes loses bits and it causes it to lose sync. I'll think how to do it.

I haven't gotten your original email? Weird.

What modulation and symbol rate are you using?

Me neither. Maybe it is stuck in the moderation queue – due to not being subscribed during that time or size of the attachment.

I'm subscribed since quite some time and files are just 3K + 5K. Trying to resend

They are not on the list.
Make sure that they are sent as text/plain MIME type attachments and/or inline attachments. I have no idea if any of that is possible to set for gmail, my experience is that gmail is consistently completely useless for people trying to work sanely with attachments and mailing lists.

custom FSK variant at 10ms per bit. I'll just introduce a 5ms tone to split bytes.
