And I cannot enter tpl command
If you cannot read from that picture just open it from another window.
I also have a bricked Archer C7v2 that I've been trying off and on to get a serial console working on. I have 5+ different USB<->TTL devices and I've never gotten anything out of any of them until yesterday when I finally got some output using an old(er) school Cable Matters device that is USB A on one end and DB9 on the other. The problem is that the output is all garbage. This is the last few lines before the output stops:

I'm only hooking up RX, TX and GND and I have RX->TX and TX->RX. If I reverse those I get no output. I also tried an 840 ohm resistor between RX and VCC on the main board as suggested on the open-wrt page and that does two things: doesn't give any output and causes the power on light blinking sequence to drastically shorten.
I have puTTY set to 115200 baud, 8 data bits, 1 stop bit, no parity, flow xon/xoff, remote character set to UTF-8 and from a suggestion on another page on open-wrt, I have checked the option to "Enable VT100 line drawing even in UTF-8 mode"
I'm hoping you can tell me how you got your serial working and/or anyone else who can tell me what I'm missing/doing wrong.
Thanks!
