Using rxtx, i cant get past square one on my current system. Ive been |
2 |
trying on and off for the last few months to get some onewire devices |
3 |
working with my system but havent had any luck. So in the process of |
4 |
troubleshooting, I built and ran this fairly simple program: |

As soon as I try to open any port, a native exception is thrown, which |
9 |
is a flippin pain. |

I am in uucp, and to be sure I have applied liberal permissions to the |
12 |
serial devices in dev and the contents of /var/lock (and /var/lock |
13 |
itself). ie |

|

lstewart@yotta ~/Desktop/javaxcomm $ ls -al /dev/ttyS{0,1} |

crwxrwxr-x 1 root tty 4, 64 Feb 23 09:56 /dev/ttyS0 |

crwxrwxr-x 1 root tty 4, 65 Feb 23 09:56 /dev/ttyS1 |

lstewart@yotta ~/Desktop/javaxcomm $ ls -al /var/lock/ |

The answer MUST be simple...this is such a basic task and Linux has |
31 |
such a long history in interfacing with serial devices .... i mean |
