Using rxtx, i cant get past square one on my current system. Ive been trying on and off for the last few months to get some onewire devices working with my system but havent had any luck. So in the process of troubleshooting, I built and ran this fairly simple program:
http://www.java2s.com/ExampleCode/Development-Class/OpenaserialportusingJavaCommunications.htm As soon as I try to open any port, a native exception is thrown, which is a flippin pain. I am in uucp, and to be sure I have applied liberal permissions to the serial devices in dev and the contents of /var/lock (and /var/lock itself). ie [EMAIL PROTECTED] ~/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 [EMAIL PROTECTED] ~/Desktop/javaxcomm $ id uid=1000(lstewart) gid=442(media), groups=5(tty),7(lp),10(wheel),11(floppy),12(mail),14(uucp),16(cron),18(audio),19(cdrom),20(dialout),21(ftp),27(video),35(games),80(cdrw),81(apache),100(users),245(slocate),442(media),446(plugdev),449(camera) [EMAIL PROTECTED] ~/Desktop/javaxcomm $ ls -al /var/lock/ total 5 drwxrwxr-x 2 root uucp 104 May 4 17:23 . drwxr-xr-x 19 root root 552 Apr 20 23:29 .. -rwxrwxr-x 1 root root 0 Mar 27 22:18 .keep -r--r--r-- 1 lstewart media 11 May 4 17:23 LCK..ttyS0 The answer MUST be simple...this is such a basic task and Linux has such a long history in interfacing with serial devices .... i mean RS-232!! I know im missing something very simple.....anyone??? -- gentoo-user@gentoo.org mailing list
