You could use minicom to test the cable. Since your gigastudio has two |
| 9 |
serial ports, you can two minicoms on that machine (one on ttyS0, the |
| 10 |
other on ttyS1 - IIRC you have to restart minicom after you changed the |
| 11 |
port). |

If you can send some text from one minicom to the other with e.g. 115200 |
| 17 |
bps, you could try sending a file between them. That should work without |
| 18 |
errors (or with nearly no errors). |

Yes, I think it would. But you can test it with the method from above. |

setserial -a /dev/ttyS0 |

setserial -a /dev/ttyS1 |

should show your UART (e.g. 16550A), not "unknown". |
