because of that, a call to cam.begin(115200) will not correctly set the variable "baud".
The uint16_t variable "baud" will only hold values up to 65535 (2^16-1).
I recommend converting that variable to a uint32_t.

Now if only I could get the actual baud rate to change! The camera is slow at 38400.

Inspect the declaration and uses of the uint16_t variable "baud", especially the cam.begin(115200) path. Confirm that the value can represent 115200 and verify whether the camera's configured baud rate changes as expected.
