I'm trying to get the Interface COM3 to work. Hardware seems to be wired correctly.
COM1 and COM2 are working fine.
On COM3 I dont receive any data in my program. While sending data by a terminal program, I always receive the same string I sent, back.
Is there a connection problem? Or do I have to configure somewhere in registry?
Unfortunately there is no information in debug output while starting board in terminal.
Only Serial1 is mentioned:
> Drivers\Builtin\Serial1 - OFF
In registry all 3 serial interfaces are active.
Thanks a lot in advance...
Best regards, Andy
