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.

Several parts of the code are in assembly. The boot loader baud is 76800, that is what I have been using during development.
What "bug" are you referring to? I have tested up to 230400 baud using a PCI-e serial card. I run my Amiga every day at 115200 baud.

You set the serial speed at 115200 baud with at*b115200 and save with at&w. Working until you do a reset with a power cycle. And now the wimodem don't communicate at all. It set a unknown serial speed that isn't a standard rs232 speed (or bad data format). I got garbage characters on screen at all possible speeds. I use the internal COM of motherboard. Tomorrow i test with a usb to serial converter. At 19200 i don't have this issue.

So, it's just 115200 baud that has this issue? Not 19200, 38400, or 57600? I haven't tried saving at 115200. My baud rate is saved as 57600. I switch manually from 57600 to 115200 when I use the Amiga, because I switch device drivers as well. I will try saving the baud rate at 115200 and see what happens.

Tried now at 38400 and 57600 bps , is working. It'is only on 115200 speed. I also used an USB to serial converter (PL-2303 chip) and same results.

OK, I see what the problem is. I will have to re-write the baud rate handler. The save routine doesn't support baud rates higher than 65535 baud.
