[ts-7000] TS-7250: Console on COM1(ttyAM0) and COM2(ttyAM1)

["Horst" <>]

I'd like to get data from COM2 by starting a program in the console (at COM1).
But a console is also available on COM2, so that I can't get data there.
The jumpers are in default position (console enabled on COM1).

Is this a normal behaviour?

What to do to use COM2 as "data"-interface?

If logged in on COM2 you can see on COM1:
Technologic Systems TS-LINUX/arm 7.0
ts7200 login: root
login[82]: root login  on `ttyAM0'
$
$
$ login[83]: root login  on `ttyAM1'


Thanks!

Demo for COM2:
#include <stdio.h>
#include <string.h>
#include <termios.h>
#include <fcntl.h>

int main( void )
{
   int fd;
   struct termios options;
   int n;
   char buff[255];
   /* Open Port */
   fd = open("/dev/ttyAM1", O_RDWR | O_NOCTTY | O_NDELAY);
   if(fd == -1)
   {
      printf("ERROR Open Serial Port!");
   }  
   else
      fcntl(fd, F_SETFL, 0);
   /* Serial Configuration */
   tcgetattr(fd, &options);         // Get Current Config
   cfsetispeed(&options, B115200);  // Set Baud Rate to 115200
   cfsetospeed(&options, B115200);
   options.c_cflag &= ~CSIZE;       // Set Data Bits to 8 Bits
   options.c_cflag |= CS8;
   options.c_cflag &= ~PARENB;      // No Parity (8N1)
   options.c_cflag &= ~CSTOPB;
   /* Save The Configure */
   tcsetattr(fd, TCSANOW, &options);
   
   do
   {
      n = read(fd,buff,10);               // Read Data From Serial Port
      if(n>0)
      {
         printf("From Serial : %s",buff); // Print Out
         write(fd,buff,strlen(buff));     // Write Data Out
      }
   }while(strncmp(buff,"bye",3));         // If user say bye then Exit

   close(fd); // Close Port
   return 0; // End Program
}
