Hi Jonny, The lock file is something I don't experience in Windows with RXTX but I've heard others talk about it. Apparently if you manually delete it first before running it will work. From your message it looks like it's at /var/lock/LCK..ttyUSB0
(Why two dots in the filename?) Our next version will have the option to work with Bluez for Linux, which is much better than RXTX. We also added an option for Java Comm API support. - Brian ----- Original Message ----- From: "jonny Linux" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Wednesday, December 13, 2006 10:25 AM Subject: Re: [Lejos-discussion] NXT ticks when using motors with icommand > On 12/12/06, Brian Bagnall <[EMAIL PROTECTED]> wrote: >> >> 30 degrees is a pretty small number.
