Wine can't see some USB adapters but IME can always see real UARTs. Be aware that the Linux kernel will always create /dev/ttyS[0-3] at boot time regardless of whether the computer hardware actually has any serial ports, but of course they won't work. Its worth checking whether Linux is recognising your serial ports: Serial ports on the motherboard or a PCI serial adapter card should be recognised at boot time: run "dmesg | less" and scroll through the boot report it displays. This will show you how many UARTS Linux has found and activated. If you have more than 4 installed, you'll need to provide the kernel argument: 8250.nr_uarts=n at boot time, best done by editing /root/grub/grub.conf - 'n' is the number of serial ports you have installed. Some hints on editing the GRUB config file are here: http://www.libelle-systems.com/free/grub/visible_menu.html USB adapters are different: their devices are called /dev/ttyUSBn where 'n' is 0 for the first one and is incremented for each adapter. These are created as the adapter is plugged in and destroyed as it is removed: you can try using a symlink but bear in mind that it will be invalid when the adapter isn't plugged in. As I said, I haven't had any joy with USB adapters, though the Belkin is said to work with Wine. I bought a six port serial PCI card which 'just worked' once I'd added the kernel argument to say I have six serial ports. This works without needing any COMn: symlinks and has done over many Wine versions and several RedHat Fedora upgrades. Martin
