BTW, it applies to all programs, e.g. Kermit and minicom, as well as WINE apps that are run by normal users. With current, udev-based, kernels its necessary to reset the permissions of /dev/ttyS[0-9] after every boot. I added a local rule file to /etc/udev/rules.d: $ cat 51-local.rules # # Locally defined rules. # # # Give world read/write access to ttyS* and ttyUSB* serial devices # KERNEL=="tty[A-Z]*", GROUP="uucp", MODE="0666" $ This works under Fedora 6 through Fedora 10. Under earlier releases it was sufficient to add a line containing: chmod uga+rw /dev/ttyS* to /etc/rc.d/rc.local so it got run at boot time, but IIRC this doesn't work with UDEV since all the /dev/ttyS* devices are no longer created ar boot time. On Fedora 10 and WINE 1.1.23 this works with all real serial ports (I have two on the mobo and another 4 on an IPC card) without needing to add COMn: symlinks to the dosdevices directory. I have never been able to access USB serial adapters from WINE, probably because they need special Windows drivers. Martin
