WiModem232 Won't Emergency Reset

[Gods]

The code is in C and assembly.  The default baud rate of the boot loader is 76800, which is available on Windows if your terminal program supports it.

What parts of your code use ASM ?
The boot loader (bootrom) baud rate today isn't 74880, with a 26 MHz crystal ? I think the 76800 baud rate is with a 40 MHz crystal and now all ESP8266 units use 26 MHz crystal.
Back to the suject, have you see this 115200 serial bug? I tested all the standard serial speeds (until 115K,my serial device don't go higher) and no AT modem answer.
