> The serial boot loader fails to process some newtmgr commands:
> 1. The image list response is too large for the outgoing buffer.
> 2. The "new" newtmgr sends large image chunks in its image upload requests.  These chunks are too large for the serial boot loader's input buffer.
> The fixes are as follows:
> 1. Increase the outgoing buffer size from 48 to 80.
> 2. Increase the incoming buffer size from 128 to 512.
> 3. Return an error rather than overrun the output buffer.
