CRLF, not LFCR.

Sorry, that's what I meant.

- Mon Aug 03, 2015 10:13 am #24906 I'm guessing it's toast, huh? I mean, everything works, but the serial comms are hosed... I don't know what else to try.

If I set it to 9600, I get back "AT". If it was shorted, I'd get back what I sent regardless of the baud, correct?

Have a look here wiki/doku.php?id=getting-started-with-the-esp8266

You will see

If your UART Tx is correct, typing ”AT“ followed by control-m and control-j, yes both carriage return and linefeed are needed, should return an ”OK“. And you are now ready to start working with the ESP8266. It should echo the characters as you type them.

Hope that helps . I started with that intro

I did manage to get the bootloader to spit out some info (I had to switch console applications on OSX, coolTerm wasn't cutting it) This is what the ESP had to say

Code: Select all ets Jan  8 2013,rst cause:1, boot mode:(3,7)

load 0x40100000, len 612, room 16
tail 4
chksum 0x12
load 0x3ffe8000, len 788, room 4
tail 0
chksum 0x50
load 0x3ffe8314, len 264, room 8
tail 0
chksum 0x4a
csum 0x4a

2nd boot version : 1.1
  SPI Speed      : 40MHz
  SPI Mode       : QIO
  SPI Flash Size : 4Mbit
jump to run user1

When I go back to 9600 baud, I do get the "ready" prompt, but no amount of fiddling with AT commands can get it to reply. Is the answer staring me in the face?
