|
Hi,
I am having a problem with my serial ports under udev: The problem is illustrated by the display below:
| Code: |
theodor dev # ls ttyS* -al
lrwxrwxrwx 1 root root 5 26 jan 09.09 ttyS0 -> tts/0
lrwxrwxrwx 1 root root 5 26 jan 09.09 ttyS1 -> tts/1
lrwxrwxrwx 1 root root 5 26 jan 09.09 ttyS2 -> tts/2
lrwxrwxrwx 1 root root 5 26 jan 09.09 ttyS3 -> tts/3
theodor dev # ls tts/* -al
lrwxrwxrwx 1 root root 8 26 jan 09.09 tts/0 -> ../ttyS0
lrwxrwxrwx 1 root root 8 26 jan 09.09 tts/1 -> ../ttyS1
lrwxrwxrwx 1 root root 8 26 jan 09.09 tts/2 -> ../ttyS2
lrwxrwxrwx 1 root root 8 26 jan 09.09 tts/3 -> ../ttyS3

As you can imagine, trying to sync my old serial Palm pilot using this setup is not very easy. How do I fix it?
| Code: |

That's odd. I have actual devices in /dev for ttyS* | Code: | wprgen2@adhara ~ $ ls -l /dev/ttyS*
crw-rw---- 1 root uucp 4, 64 2007-02-15 10:06 /dev/ttyS0
crw-rw---- 1 root uucp 4, 65 2007-02-14 10:26 /dev/ttyS1
crw-rw---- 1 root uucp 4, 66 2007-02-14 10:26 /dev/ttyS2
crw-rw---- 1 root uucp 4, 67 2007-02-14 10:26 /dev/ttyS3 |
My PDA is an old Palm VIIx and also uses a serial cradle. I use jpilot, too.
One wrinkle is that I just upgraded my amd64 system from udev-087-r1 and coldplug to udev-104-r11 (and no coldplug). This upgrade broke my sync because /dev/ttyS0 was now owned by root and in group uucp with permissions of 440 (rw-rw----). Since I wasn't in the uucp group it was failing. I just added myself to the uucp group (and logged out and back in to make it take effect) and all was happy again.
So check your version of udev/coldplug to see what's up with creating those devices. |
