/dev/??? for assabet


  I try to dump the debug msgs(printf) to the serial port, just follow 
redboot.
But how do I figure out the name? I tried /dev/tty0,1 also ser0,1,
all with no luck.


#include <cyg/io/io.h>
#include <cyg/io/serialio.h>
#include <cyg/error/codes.h>
#include <stdio.h>
int main(void)
{
  cyg_uint32 length;
  Cyg_ErrNo error;
  char test_msg1[]="This is a test message!\n";
  cyg_io_handle_t serial_port_handle;
 
  error = cyg_io_lookup("/dev/tty1", &serial_port_handle);
  if (error == ENOERR) {
    length = strlen(&test_msg1[0]);
    cyg_io_write(serial_port_handle, &test_msg1[0], &length);

  }
  printf("andrew xiang!\n");
  return 0;
}
