Can't really tell what the baud rate is by looking at the scope. It's an old, old Hitachi analog scope from the 1970s or so, can't freeze the signal or do any fancy visualizations with it. With an irregular signal, all I see is 2 voltage level lines connected by edges here and there. 😀
When I said "feeding right into..." I meant not using the pre-made cable but instead using my own homemade one. It did connect all 3 wires (gnd, Vcc and signal). Well the surrogate Vcc that is pin 2 anyway. 😀
I'll have to double check on the fuse settings, but that'll be some other day. I entered a pretty big crunch at work today, likely to go into the weekend and possibly beyond... Just got home, barely had the strength to have dinner and getting to bed right after I write this.
I/O, I/O,
It's off to disk I go,
With a bit and a byte
And a read and a write,
I/O, I/O
