I just went through this. The tty devices are oned by root and belong to the group uucp. I had to (as root) chmod 666 /dev/ttyS0, which in my case is the serial port my modem is on. I found that adding myself to the dialout and uucp groups was not enough, because the tty only had write permissions for the owner (not the group or world). If you add users to the dialout and uucp groups, you can probably get away with chmod 660 and be a little more secure.

Hi all

Could someone tell me how one can change the permissions of wvdial to allow a user to access the modem? According to the SuSE book if you add the user to the groups uucp and dialout it should work, however I still get the message that access to the serial port, in my case /dev/ttyS0, is denied. So I guess my question is really, how does one change the permissions of the serial port?

Thanks

Paul
