I have done some interesign experiment…

On this side there is a nice overview of the AT!MAPUART command…

I have set UART1 (my problem UART) as output for the Linux Console (with AT!MAPUART= 16,1)

While bootup of the module, the module now shows his complete boot process in my terminal.  
(You can see here)  
[WP7607 Booting !MAPUART 1,16 Linux Console.txt](https://mangoh.discourse.group/uploads/short-url/o3AwcQbQGuqKB44isqQPoJ1udnB.txt) (14.2 KB)

So the transmitt hardware of the WP7607 is working perfectly.  
Iam also shure that, the receive hardware to the module is working.
