I have a serial receipt printer connected to my server. Printing System is CUPS on SuSe 10.2. Until upgrade it was working OK. Since then how ever I often get this message:
"Unable to open serial port device file "/dev/ttyS0": Permission denied"
And what permissions does it has at that moment?
Just to be sure I gave it 777 but that did not make any difference. After I deleted the printer in CUPS and then installed it using Yast permissions were changed to crw-rw-rw- As I explained in my other post the only way how to make the printer working is to delete it in CUPS and then install it with Yast. It does not work if I simply delete it in Yast and then install it again or do the same in CUPS.
from CUPS. I have to play with it a little set up the printer again and it works for a while. Then it stops working again. How do I make it working permanently?
My guess would be one of those things like resmngr grabbing it for use by the desktop user (like a modem). Perhaps you have desktop gadgets to setup the modem: remove them. I'm thinking of kinternet and family. Or use Yast to tell it the modem is at ttyS1 perhaps. If there exists a /dev/modem link make sure it points somewhere else.
I do not have a modem but I will check this out.
