You need some code similar to the following in the serial driver: #ifdef CONFIG_DEVFS_FS serial_driver.name = "tts/%d"; #else serial_driver.name = "ttyS"; #endif Of course if the original device nodes were named /dev/ttyZ0 etc then you want "tts/Z%d". Look at the Cyclades and Stallion drivers for examples of it being done correctly. Or tell me exactly the details of what you want and I'll send you a patch. -- If you send email to me or to a mailing list that I use which has >4 lines of legalistic junk at the end then you are specifically authorizing me to do whatever I wish with the message and all other messages from your domain, by posting the message you agree that your long legalistic sig is void.
