PicoMOD7 serial ports

      PicoMOD7 serial ports

      Dear F&S support,

      on PicoMOD7 Starterboard (Startinf) there are two serial ports. Connector COM3 is used for debugging console as dev/ttyS0. Is this right so far? I can log into this console from PC with putty - it's working. Now I need to use the second serial port on connector COM1. How can I use it? On PicoMOD /dev there are ttyS0 to ttyS3 devices. When I try to read/write to ttyS1 to ttyS3 "Input/output error" will be returned. When I try to read/write to ttyS0 "getty: ttyS0: TIOCSCTTY: Inappropriate ioctl for device" will be returned. That's why I think ttyS0 is used as the debug console. So what do I need to do to get the COM1 port working (I'm able to compile changes to the kernel settings by myself if necessary).

      Kind regards and a nice weekend.
